The Big Bang Theory

The Holiday Summation - S10-E12

Corrected entry: Penny finds a place where they can cut a tree themselves. She states that Leonard let the axe slip from his hands but when the tree slips in the roof, we can see that the tree was cut with a chainsaw by the linear cut on the wood.

Correction: It was a farm that lets people cut down their own tree with an axe, but after you cut it down, there is normally a place at the front where you pay that will give a clean cut with a chainsaw so that the tree goes cleanly into a stand. They also will typically clean up the lower branches for the same reason.

The Junior Professor Solution - S8-E2

Corrected entry: When Howard is asking Sheldon engineering questions, the first question is "How do you quantify the strength of materials?" Sheldon answers "Young's Modulus," and Howard admits that is correct. But it's not correct - Young's Modulus quantifies a material's rigidity, not strength.

00:17:10

Correction: Young's modulus does quantify strength. Rigidity is measured by shear modulus. Strength is quantified by Young's Modulus.

The Bad Fish Paradigm - S2-E1

Corrected entry: When Sheldon mentions to Leonard, Raj, and Howard that he is moving out, Raj asks Leonard "Did you pronounce the 't' in often?" This statement in context implies that it makes Sheldon angry when someone pronounces the 't' in often. However, Leonard and other characters do this multiple times throughout the series with Sheldon never commenting on it.

Ashish_Agrawal

Correction: Sheldon is also very particular about things in certain episodes. It's not out of character for certain ticks to disappear and reappear throughout.

The Geology Elevation - S10-E9

Corrected entry: A person wearing a blue shirt is seen poking out behind the refrigerator for a moment when Leonard is talking.

00:12:55

Correction: That's Raj wearing a blue jacket getting condiments.

Greg Dwyer

The Friendship Algorithm - S2-E13

Corrected entry: When Penny asks Leonard how Sheldon met Howard and Raj his answer is a long science answer that means he has no clue. That is incorrect since another episode reveals Leonard met them at school and brought them to the apartment.

00:05:00

bcrd500

Correction: The answer Leonard gives to Penny is actually a correct scientific statement, and it doesn't indicate that he's clueless. He says "kinda like carbon atoms for a benzene ring, proximity and valence electrons". This is a correct statement. Carbon atoms are small and have 4 valence electrons, i.e., they can form 4 bonds. Due to catenation, carbon atoms have a very strong tendency to bond with other carbon atoms. Similarly, Leonard's statement suggests that they worked at the same place (hence proximity) and they were all seeking friends (valence electrons). Hence they became friends.

The Cooper-Hofstadter Polarization - S1-E9

Corrected entry: Howard explains how the signal travels to the lamp via various means and clicks to switch the lamp on. There is then a delay of around 1 second. However when he does the same thing for the stereo the sound starts instantly.

00:00:10

A Demon Premium member

Correction: Technically, when you use a network for the first time, there are many steps involved like creating a VPN, matching IP addresses, etc, hence the delay. Once you have connected and used it at least once, the go-betweens don't exist, hence there is no delay.

The Rothman Disintegration - S5-E17

Corrected entry: After Sheldon has told Barry about the rules of Rock/Paper/Scissors/Lizard/Spock for the first time, Barry then replies "I'm sorry, can you repeat that." When he says "repeat", he correctly pronounces the "r." However, it has already been established throughout the series that Barry pronounces all his Rs like Ws due to his speech impediment.

Casual Person

Correction: Barry doesn't always mispronounce the letter R. It can happen with certain Rs and Ls.

The Holographic Excitation - S6-E5

Corrected entry: When Sheldon has the tea kettle at any time, there are stage lights reflected on the pot.

bobthedancingdonut

Correction: The pattern on the teapot suggests that the spots are actually overhead lights in the kitchen. The patterns are constant throughout the scene and the same at every angle whereas crew's spotlights have different placements for different angled shots.

The Excelsior Acquisition - S3-E16

Corrected entry: Penny doesn't know who Stan Lee is in this episode, though earlier in the series she not only knew who he was but met him at the Cheesecake Factory and had him sign a napkin for Sheldon.

Correction: The signed napkin (from s02e11 "The Bath Item Gift Hypothesis") was from Leonard Nimoy (who played Spock) whom Penny met at the Cheesecake Factory, not Stan Lee.

Bishop73

The Zazzy Substitution - S4-E3

Corrected entry: The proposition that danishes wouldn't exist if Copenhagen were flooded is wrong, because "danishes" were created by Austrian bakers. They are called danish in English-speaking countries because they're very popular in Denmark. The Danish word for this pastry is wienerbrød, which translates to "Viennese bread."

Tanngrisnir

Correction: The origin of the Danish pastry is often ascribed to a strike amongst bakery workers in Denmark in 1850. The strike caused bakery owners to hire workers from abroad, among them several Austrian bakers, who brought along new baking traditions and pastry recipes.

The Locomotion Interruption - S8-E1

Corrected entry: When they're driving back from Arianna, the road is a stupidly big bend for several shots, then the shot changes and it's suddenly straight and a much lighter tarmac.

Correction: After Amy says "How could you leave like that without saying goodbye and then call Leonard instead of me", and the shot changes to Sheldon looking at Leonard and then back to the three of them, it can be seen in the background that at the turn, the tarmac quality actually changes. Thus it is originally there and the footage is continuous.

The Barbarian Sublimation - S2-E3

Corrected entry: When Penny is having trouble unlocking her apartment door, she says she is waiting for the locksmith but she never took the time to call the locksmith.

Correction: She had already called them before we (and Sheldon) see her struggling with her door.

THGhost

The Friendship Algorithm - S2-E13

Corrected entry: When Sheldon and Barry are rock climbing, Sheldon looks down and shouts in fear. When Barry asks "You all right there Cooper?", Sheldon answers "I feel somewhat like an inverse tangent function approaching an asymptote." An inverse tangent function approaches its asymptote in the horizontal axis, not the vertical.

00:15:55

Correction: The vanity card at the end explains the joke. "A linear asymptote is essentially a straight line to which a graphed curve moves closer and closer but does not reach. In other words, given a function y=fn (x) with asymptote A, A represents a number that, no matter how big (or, given the function, small) you make x, y will never make it to A. The particular example Sheldon quotes is the inverse Tangent function, or Arctangent, which has two asymptotes. If you graph it, it sort of looks like a horizontal S. No matter how big you make x (that is, how far you move to the right [that is horizontally]), the function is never going to hit that top line (π/2), and no matter how small x gets (moving to the left), y is never going to be smaller than - π/2" Sheldon is saying he will never reach the top.

Bishop73

The Higgs Boson Observation - S6-E3

Corrected entry: When Amy is putting on make up with Penny's help, where Amy says "I'm going to video chat Sheldon" she is not wearing glasses. The shot moves to capture Penny's face and Amy is wearing glasses, then the next shot shows Amy is not wearing her glasses.

00:09:00

Correction: After Amy says "I'm a maneater now", she removes her spectacles. There is no evidence of her wearing them again.

The Codpiece Topology - S2-E2

Corrected entry: When Leonard and Leslie are talking about assuming a relationship, in the cafeteria, the angle of the straw sticking out of Leonard's soda can continually changes throughout the whole scene.

00:06:05

Hamster Premium member

Correction: This is due to the multiple camera angles used in the scene. The straw doesn't change angle.

A Demon Premium member

The Barbarian Sublimation - S2-E3

Corrected entry: When Sheldon is helping Penny with the game, we see Leonard, Howard and Raj discussing what's happening. However at this point Penny is still in the room and Raj has not been drinking so shouldn't be able to speak.

00:07:40

A Demon Premium member

Correction: Raj is whispering to the other two so Penny doesn't hear him.

MasterOfAll

He's not whispering and when he does whisper in front of Penny he covers his mouth.

A Demon Premium member

The Military Miniaturization - S10-E2

Corrected entry: When Raj and Howard are trying to decide whether to accept Col. Williams' offer, they can't think of any lawyers to ask for help with potential legal issues; they both seem to be forgetting that they do know a lawyer: Raj's sister Priya.

Cubs Fan Premium member

Correction: Given how things ended with Priya and Leonard, it probably would have been very awkward for both of them. In addition, she knows far more about Indian law than American law.

Greg Dwyer

The Boyfriend Complexity - S4-E9

Corrected entry: Penny's father says, "I want grand kids before I die, and I want them to grow up in a house without wheels," but in season 2, E20, Penny asks Leonard to buy a comic book for her 13 year old nephew. Her nephew would be her father's grandson.

Correction: Her mother may have had a child with another man before marrying her father, which would make the nephew a step-grandson and not a "real" one in her father's eyes.

Captain Defenestrator Premium member

The Hesitation Ramification - S7-E12

Corrected entry: When Sheldon comes to tell Leonard and Penny his perfect joke he is wearing a plain green T-shirt, but when Penny leaves and he begins to tell Leanord about it, his shirt now has a black symbol on it.

The_Iceman Premium member

Correction: The symbol is there the entire time. It's just very difficult to see.

Greg Dwyer

The Sales Call Sublimation - S9-E12

Corrected entry: After the opening credits, Penny walks into the room talking about a doctor she's not been able to see, saying "I've been trying to get him for months". A few seconds later she says the doctor is a woman.

00:02:30

Alex Seven Adderley

Correction: Penny says "I've been trying to get in for months."

The Romance Resonance - S7-E6

Corrected entry: When Sheldon realises his mistake in reading sq centimeters as sq meters he says "I am off by a factor of 10,000" when in actuality such a mistake would be by a factor of 100.

Correction: No, he's right - 2cm x 2cm (for example) would be 4 sq cm. 2m x 2m (200cm x 200cm) would be 40,000 sq cm - off by a factor of 10,000.

Show generally

Corrected entry: Bernadette says the thing she loves most about Howard is his chest hair to which the other girls say "he has a hairy chest?" and she replies "Nope, just one" but a few episodes later they are in bed and Howard has a full chest of hair.

The_Iceman Premium member

Correction: She's just making a joke.

THGhost

No she wasn't. The look on her face shows she was being serious, plus her character at that time was portrayed as weird and "kooky."

The_Iceman Premium member

Bernadette always has a serious demeanour about her when it comes to Howard. It. Is. A. Joke.

THGhost

A serious demeanour but making a joke? I get the impression you haven't even watched the scene in question.

The_Iceman Premium member

Dude, it's a joke. Move on.

THGhost

And you assume too much, I wouldn't be correcting this if I hadn't watched the scene.

THGhost

Dry humour works best when delivered deadpan.

How anyone wouldn't get that this was a joke is beyond me. Bernadette is exaggerating about Howard's chest hair because he isn't the most masculine of men.

You look at her eyes, you look at her face and you listen to her voice. Anyone can see it is an excited, almost turned on expression and tone. Your correction is based solely on your assumption and opinion of the situation. Mine is based on actual physical evidence and what is said.

The_Iceman Premium member

Watch the scene you want to correct, don't just assume based on memory.

The_Iceman Premium member

I've watched it, and there's zero difference between someone making a dry joke and someone being serious. The only distinction is factual content, and given that we see he's got a hairy chest, it's clear that she must just be making a flippant comment. She likes his chest hair, and when Penny questions it Bernadette takes the opportunity to say something that amuses herself. It's a passing aside that they move on from, and this isn't a mistake.

Jon Sandys Premium member

The Electric Can Opener Fluctuation - S3-E1

Corrected entry: At the end of the episode, Sheldon runs off to Texas. That would be impossible in the short time frame the episode was set in. Especially since they live in Pasadena, California. California is 18 hours away by car from Texas. It has also been stated previously that Sheldon dislikes cars and airplanes a lot.

Correction: Just because he dislikes planes, doesn't mean that he will never go on one, as proven by him traveling by plane to Texas with Howard.

Greg Dwyer

The Misinterpretation Agitation - S8-E7

Corrected entry: When the guys are locked in the basement, the door hinges are on their side. You would think a theoretical physicist, experimental physicist, astrophysicist, and NASA engineer could together figure out to simply take the pins out of the hinges.

Correction: It's not that they couldn't do it. It's that they're in a room full of stuff they find awesome. They're having too much fun to try that hard. They don't care if they get out.

Greg Dwyer

The Solder Excursion Diversion - S9-E19

Corrected entry: It's revealed that Sheldon rents out a storage unit that contains literally everything that he has ever owned in his lifetime. How is it that nobody else has ever known about this? He doesn't drive, nor does he take public transportation, and we can assume that he must make regular trips there to store any item that he no longer needs/uses. So he would surely need to be driven there by someone, most likely by Leonard, and he obviously couldn't keep it a secret as to why he needs to go there.

Correction: While Sheldon does not like public transportation, he does take the bus when needed. There are numerous mentions of "bus pants" and "bungee cording himself to the seat" to prove he will take a bus when he has to.

SantaJim

The Countdown Reflection - S5-E24

Corrected entry: When they are marrying Bernadette and Howard, Raj is speaking straight to the women without alcohol. And it's the same people as he normally can't talk around.

Correction: Although no alcohol is shown onscreen, it doesn't necessarily mean he hadn't already drank any alcohol already. There's nothing there to say whether or not he quickly had a drink before the ceremony, off-screen, whilst they were setting up on the roof.

Casual Person

The Panty Piñata Polarization - S2-E7

Corrected entry: Penny takes Sheldon's onion ring and holds it with 2 hands. Camera cuts and one is hand is down in her lap.

00:05:00

A Demon Premium member

Correction: The camera doesn't cut from Penny having two hands on the onion ring to just one hand. After Penny picks up the onion ring with two hands, the camera cuts to Raj squealing at her for a moment. She could have easily let go of the onion ring and put her hand down on her lap during this shot.

Casual Person

Show generally

Corrected entry: Several times throughout the show, Leonard makes reference to having sleep apnoea, a condition where the airways close up when you are asleep and you stop breathing for periods of time before your body's reflexes kick in and wake you up. However we also see him sleeping numerous times but he doesn't have any form of cpap (Continuous Positive Airway Pressure) machine. This is vital for anyone who has sleep apnoea as it pumps air into the users airways via a nasal cannula or face mask to keep the airways open and stop the user from stopping breathing. Since sleep apnoea in the most extreme cases can cause death (depending on type of sleep apnoea) a cpap machine is vital and should be seen whenever we see Leonard sleeping or in bed.

A Demon Premium member

Correction: There is no mistake simply because he chooses not to use one (if he even owns one). There are individuals with sleep apnea who don't use them and just deal with waking up in the middle of the night. If Leonard says he has to use a CPAP machine every night and then is seen not using one at night, that could qualify as a mistake, but this isn't the case.

The Financial Permeability - S2-E14

Corrected entry: When using the whiteboard at the beginning, Raj writes "7:11" on the board with a red marker. Later on when Sheldon returns to the apartment with Red Vines, this has vanished from the whiteboard although nobody rubbed it out.

00:01:10

Hamster Premium member

Correction: There is a red smudge where 7:11 was written. There was enough time for Sheldon to go out get Red Vines, so there was time for him to rub it off when on his own.

A Demon Premium member

The Bat Jar Conjecture - S1-E13

Corrected entry: Sheldon is very particular about sitting in his spot and not allowing anyone else into his spot. We learn later on in the series that he has been this way since Leonard moved in. However at the very end of this episode, we see Leonard sat in Sheldon's spot and Sheldon sat in the arm chair.

00:19:00

A Demon Premium member

Correction: At the start of the scene, Sheldon attempts to sit in his spot, but Leonard doesn't let him, because his Physics Bowl trophy is sitting there and then Leonard moves slightly onto Sheldon's spot to make fun of him using the trophy. Presumably, he is just sitting on the arm chair because Leonard wouldn't move and he is just sitting in that seat reluctantly.

Casual Person

The Codpiece Topology - S2-E2

Corrected entry: Sheldon's battery runs low during Leonard's date with Leslie so he gets an extension cord but leaves the door open. As he goes down the stairs the extension cord unwinds until he can't go any further and attempts to pull it. Then Leonard gets to shut the door easily like there is no extension cord plugged into the outlet and leading out of the apartment.

00:11:20

Yesser Rabhi

Correction: Having just watched this the lead goes slack and under the door.

A Demon Premium member

The Jerusalem Duality - S1-E12

Corrected entry: At the start when Sheldon and Leonard are sitting at the table, and then talking with Dennis, their soda cans on the table keep rotating themselves and the straws in them change position a couple of times too.

00:01:00

Hamster Premium member

Correction: The rotating of the cans is due to the various camera angles being used in the shot. Same with the straws.

A Demon Premium member

The Pancake Batter Anomaly - S1-E11

Corrected entry: When Leonard is standing outside the apartment his hair is tucked under the band of the wireless cam he has on his head, but when he is crawling on his hands and knees through the apartment his hair is out from under the band and is hanging in front of his face.

Jacy Sorkenn

Correction: They also find a gift bag in this time so it's clear there has been a gap of some time. Enough to sort the headband out.

A Demon Premium member

The Dumpling Paradox - S1-E7

Corrected entry: Characters in Halo games can never be decapitated, as Penny states about Sheldon's player character.

dregj

Correction: Penny says "whose head did I just blow off?" This can merely be an expression for killing someone. Not necessarily a literal reference.

A Demon Premium member

The White Asparagus Triangulation - S2-E9

Corrected entry: Sheldon is an obsessive compulsive and picky person and he picks a pre-designated seat in all places. When he enters Penny's apartment to talk to her he promptly sits on the couch, which was not where he chose 'his seat' to be in the last episode of the first season. It seems out of character that he would sit there when he has a ready-chosen spot and that his nature is as it is.

Hamster Premium member

Correction: In the season 1 episode mentioned, Sheldon says he thinks it could be his spot. Not decided, so there is no reason to assume he is completely set on that spot and he could have changed it.

A Demon Premium member

The Financial Permeability - S2-E14

Corrected entry: When Leonard returns from talking with Penny, the guys are playing Talisman. Stat counters are randomly placed on the board, when they should always be associated with cards. Then Howard rolls "double sixes" - in Talisman you advance your character by rolling a single die. Raj then acquires a sword without rolling - only the character that rolled would have acquired an item without additional gameplay.

00:13:45

Laura Hinton Dean

Correction: Fountain of Wisdom, Pool of Life, and Magic Stream all put stat counters on the board to be picked up by whomever passes by. A Horse allows one to roll two dice for movement, and Market Day or Acquisition would allow someone to acquire items out of turn.

Captain Defenestrator Premium member

The Jiminy Conjecture - S3-E2

Corrected entry: In the discussion between Raj and Howard about "shiksa goddess" plus Sheldon's later mispronunciation of the word and Howard's correction, it is never clarified that the term applies only to a Gentile girlfriend of a Jewish man. No other relationship qualifies.

MFWills

Correction: This is incorrect as it also applies to a Gentile woman who is the object of desire by a Jewish man. However, like many words, the appropriation of the word by English speakers has transformed it into any Gentile woman (although usually an attractive woman) and is as such, commonly used as a term of endearment rather than an insult.

Bishop73

The Lizard-Spock Expansion - S2-E8

Corrected entry: Sheldon suggests Rock, Paper, Scissors, Lizard, Spock as an alternative to Rock, Paper, Scissors because "Anecdotal evidence suggests that in the game of rock-paper-scissors, players familiar with each other will tie 75 to 80% of the time due to the limited number of outcomes." As a devout scientist, Sheldon would know that anecdotal evidence is no basis for reaching a conclusion because it is based on individual experience and subject to bias.

00:00:30

Captain Defenestrator Premium member

Correction: Presumably the "anecdotal evidence" is his own experience; within his group of friends they tie 75-80% of the time.

The Pants Alternative - S3-E18

Corrected entry: Sheldon claims the X-Men were named so after the X in Charles Xavier's' name. In The X-Men #1 (1963), Professor X states that mutants possess an extra power that humans do not have. Xavier then says "That is why I call my students... X-Men, for EX-tra power!"

Correction: He may be going by the movie continuity, where the X-Men DID name themselves after Charles. (Likely in an effort to "dumb it down" for Penny).

Captain Defenestrator Premium member

It could also have been deliberate on the part of the writers as a set-up for Sheldon's "C-Men" punchline.

Cubs Fan Premium member

The Bakersfield Expedition - S6-E13

Corrected entry: At the end of the episode Sheldon's sat nav voice asks "Can you name the four state capitals that are not served by the interstate system?" In fact, there are five, according to the Interstate System's website. Juneau, Alaska; Dover, Delaware; Jefferson City, Missouri; Carson City, Nevada; and Pierre, South Dakota.

Captain Defenestrator Premium member

Correction: Although there used to be 5 state capitols not served by the interstate system, the completion of I-580 means that Carson City is now served, hence there are only four, and the sat nav was correct. 580 was completed in 2012, the episode in question aired in 2013.

Shua320

The Skywalker Incursion - S8-E19

Corrected entry: Leonard refers to a never-ending game of "Bottle of Beer on the Wall" as having 'one times ten to the fourth' bottles of beer. One times ten to the fourth power is just one multiplied by itself a ridiculously large number of times, which equals one. That would be a very short game. Not a mistake a physicist would make.

PEDAUNT

Correction: One times ten to the fourth is 10,000.

The Bozeman Reaction - S3-E13

Corrected entry: In the scene where Sheldon lists the things that were stolen from the apartment, he mentions several gaming platforms including PlayStation 2 and PlayStation 3. Other than that he lists games including Final Fantasy 1 to 9. You can't play those Final Fantasy games on any of the gaming platforms he lists though (Only some HD remakes are available for the PlayStation 3, but only as downloads, so you won't be able to steal the discs because they don't exist).

00:02:45 - 00:05:15

Sabine J. Kwak

Correction: He lists the items that were stolen. Just because he lists games for consoles that weren't taken doesn't mean they weren't stolen. He either has the games but the console was not in the apartment, or he has the games and the consoles were not taken.

The Pants Alternative - S3-E18

Corrected entry: Sheldon refers to the "Hillbilly Peace Prize" in connection with Penny. Sheldon would have corrected anyone else who said such a thing. He would point out that that word "hillbilly" refers to people who dwell in rural, mountainous areas in the US primarily in Appalachia, the Ozarks, and other less well-known mountain chains. Nebraska, where Penny is from, is rural, but being a Great Plains state, has no connection at all to the term, not to mention a lack of mountains.

MFWills

Correction: Hillbilly is also an insult to those who live in farming and rural areas, which Penny's story certainly invoked.

Greg Dwyer

The Dumpling Paradox - S1-E7

Corrected entry: While the group are trying to figure out how to play Halo without Howard, Leonard jokingly suggests cutting Raj in half. Raj responds, "Oh sure, cut the foreigner in half. There's a billion more where he came from." But Penny is in the room with them, so there's no way he should be able to talk in front of her, or even if he's been drinking, the fact alcohol helps him isn't realised until the next episode, so the fact he can speak with her there should have surprised everyone, including him.

Correction: Penny is on the other side of the room and not in the conversation. Raj's comment was an aside to Howard and it can be reasonably concluded that nobody else could hear.

Knever

The Grasshopper Experiment - S1-E8

Corrected entry: Leonard wonders aloud "I wonder who's going to tell his (Sheldon's) parents they're not having grandchildren." Leonard and Sheldon have been sharing the apartment for long enough for Leonard to know that Sheldon's father has been dead for a number of years, but it is at least since S1E04, when Sheldon's mother says "God rest his soul" while talking about his father.

MFWills

Correction: Episode S01E04 ended with Sheldon asking his mother if Dr. Gablehouser is going to be his new daddy and her saying "We'll see." So he could be the other "parent." Or his mother could have met someone else between the episodes.

Captain Defenestrator Premium member

The Bon Voyage Reaction - S6-E24

Corrected entry: Sheldon gets everyone's attention by tapping a glass and saying "that's a B flat, for those that don't have perfect pitch." It's not a B flat, it's a B.

Jon Sandys Premium member

Correction: The note is a dead-on Bb, assuming the western standard of A=440 Hz.

The Hawking Excitation - S5-E21

Corrected entry: Stephen Hawking tells Sheldon he made an arithmetic mistake on page 2 of his paper. Sheldon then quickly turns pages on his paper to find the error, but Sheldon turns several pages of his paper, way past the second page, and still finds the error Stephen had noted.

Casual Person

Correction: Scientific papers number their pages differently to how one would assume. There are pages before page 1 begins which are often numbered using Roman numerals. Therefore Sheldon is correct in turning several pages to find page 2.

The Wheaton Recurrence - S3-E19

Corrected entry: In previous episodes, it's mentioned that Leonard is lactose intolerant, but at the bowling alley he eats from a plate of chili cheese fries.

Cubs Fan Premium member

Correction: Just because he's lactose intolerant doesn't mean he can't have dairy (as opposed to Howard's peanut allergy where he can't have any peanut product). In fact, in several episodes others have made fun of Leonard's flatulent as a result of him having dairy, evidence that he's had dairy products before.

Bishop73

The Pork Chop Indeterminacy - S1-E15

Corrected entry: Sheldon asks Missy why she doesn't tell her friends that he is a toll taker on The Golden Gate Bridge. There are no toll takers on the Golden Gate Bridge. Tolls are paid by credit or debit card, a prepaid account or by invoice to the registered car owner's address. There is no way Sheldon would not know this.

Correction: S1-E15 aired in May, 2008, but the Golden Gate Bridge didn't switch to all-electronic toll collection until March 2013, and the decision to convert to electronic toll collection wasn't made until January, 2011.

The Thanksgiving Decoupling - S7-E9

Corrected entry: Penny states that she did not know that a Vegas wedding is an actual wedding, however in season 5 episode 24, The Countdown Reflection, she states that she knew tons of people who got married in Vegas.

00:02:55 - 00:03:40

Correction: Just because she knows people who got married in Vegas doesn't mean she didn't know the weddings were real.

kristenlouise3

The Codpiece Topology - S2-E2

Corrected entry: Sheldon says something about drinking red bull, but he doesn't drink coffee because it's a drug, so he would avoid red bull even more.

Feather

Correction: Sheldon said that he accidentally had a sip of Red Bull. It was an accident. He didn't do it on a purpose.

The Wiggly Finger Catalyst - S5-E4

Corrected entry: Five minutes into the show, Sheldon has written down what a dice roll will tell him what to do. He rolls the dice, pauses and looks at the list to see what he has to do for that dice roll. The problem is he has an Eidetic memory and wouldn't take the time to look at the list when he can already see it in his head.

terry s

Correction: This is not at all accurate. The list he his looking at is the Cheesecake Factory menu, not one he created himself. Given the nature of the menu page Sheldon looks at, it's unlikely he's ever looked at that page before.

Bishop73

The Locomotion Interruption - S8-E1

Corrected entry: Sheldon says he was in a fire while taking a train through Des Moines. The largest Des Moines in Iowa has not had passenger rail service since 1970, and the much smaller Des Moines in Washington and New Mexico have never had it at all.

Correction: There may not be a station operating in Des Moines, but there are passenger rail tracks that go through it, stopping at Osceola. The fire could have happened on the train, as he does not specifically mention being at a station there.

Greg Dwyer

The Irish Pub Formulation - S4-E6

Corrected entry: Sheldon is playing an online game he found. He yells to Leonard "I'm trapped in quicksand, the axe is dragging me down." Leonard then tells him to "Drop axe." Shortly after, Sheldon heads to bed, but he comes back saying "I know how to get the bucket. I can turn the axe around and use the handle to reach it." However, he does not have the axe as he has already dropped it.

00:06:05 - 00:07:45

Kat Haggith

Correction: Sheldon is playing an old text and type game, many of which have only one way to beat them, so once Sheldon died, he would be sent back to the start, eventually reclaiming the Axe.

MasterOfAll

The Holographic Excitation - S6-E5

Corrected entry: Penny observes that the pencil in the hologram is sharp but looking closely at the hologram shows that it's not.

Tanngrisnir

Correction: She doesn't say that about the hologram; she says it about the actual pencil. Which it is, as Leonard puts the pointy end into the table that has equally spaced out holes in it, making it stand upright. The laser can't see below the hole in the table, which is why it doesn't appear to have a pointy end in the hologram.

The Gorilla Dissolution - S7-E23

Corrected entry: Even though the unpacked treadmill fell down the stairs and hit Howard's mother's foot whilst she was waiting down at the bottom of the stairs, there was still time for Howard's mother to move out of the way before the treadmill hit her.

Casual Person

Correction: Howard's mother is extremely overweight and would likely be unable to move out of the way in the time an average-sized person could.

The 21-Second Excitation - S4-E8

Corrected entry: Sheldon steals the 35mm movie canisters and 2 exterior metal cases for "Raiders Of The Lost Ark" so that they supposedly could see it at a later date. We then see Sheldon running with the movie canisters and cases. That would not even be remotely possible as the 2 sets of film weigh approximately 140-160 pounds. Each individual reel (of which there would be a total of 4) has a weight of somewhere between 30 and 35 pounds including the film and individual canister. If you add in the weight of just 2 canisters plus the carrying cases they come in, that's well beyond Sheldon's carrying capacity.

Correction: I worked with 35mm for 10 years. Each case weighed about 35 lbs for 3 reels.

The Cruciferous Vegetable Amplification - S4-E2

Corrected entry: Sheldon gets Leonard to read the roommate agreement, and it talks about robots. Sheldon is not a robot, he's using a Virtual presence device, therefore Leonard is under no obligation to follow the rules of the roommate agreement.

00:13:10

Correction: Like the Relationship Agreement, the Roommate Agreement is designed to be entirely for Sheldon's benefit. There's almost certainly an Exception Clause that lets him stretch the definition or alter it however he wants. Leonard would know this and probably not consider it worth fighting about.

The Dumpling Paradox - S1-E7

Corrected entry: When Penny tells Sheldon that he forgot a plasma grenade, she presses the right trigger on the Xbox controller. On Halo 3, the right trigger fires weapons, not grenades. That's the left trigger.

Brad Premium member

Correction: In Halo 3 you can change around some features of the remote, including which trigger fires grenades and weapons.

kristenlouise3

The Countdown Reflection - S5-E24

Corrected entry: There is not a snowball's chance of Howard becoming an astronaut. He suffers from Intermittent Cardiac Arrhythmia, something about which he is completely open. This is easily detectable by a simple electrocardiogram, which is a fundamental part of the many medical examinations a potential astronaut will have to pass. He wouldn't even be allowed to start basic training.

Correction: This is false. He says it is a transient idiopathic arrhythmia which by nature means it is a different rhythm but there is nothing wrong with it. Therefore would not be an issue for an astronaut.

The Large Hadron Collision - S3-E15

Corrected entry: The "Hollermus" that Sheldon allegedly makes is not actually a Swiss breakfast dish. It is in fact simply a kind of jam made from elderberries which is quite common in most German-speaking countries. Also, judging by the ingredients on the table (eggs, milk, butter) and the food on the plate, the dish prepared by Sheldon seems most likely to be an omelette with a Vienna sausage, which is in no way traditionally Swiss.

Tanngrisnir

Correction: He actually says Cholermus which is a swish breakfast dish similar to a pancake, I had to find a script online when I first heard it to figure out what it was.

The Tangerine Factor - S1-E17

Corrected entry: Penny storms into Sheldon and Leonard's apartment to throw her boyfriend's iPod out of their window and yell at her boyfriend who has just left. Raj then finds the iPod on his way in. However, according to the layout of the building with the front door being to the left of the elevator, the front side of their apartment building would be on Penny's side, so she should have thrown it out of her own apartment window. The window through Sheldon and Leonard's apartment would lead to the back.

07marsh

Correction: There's no indication from the scene that she's catching him as he is stepping out the door. He could have had his car parked behind the building and was on his way round to the front.

Jay32183

The Locomotive Manipulation - S7-E15

Corrected entry: Sheldon asks whether the train carriage has "link-and-pin" type couplers, when he would know that such couplers were outlawed by the Safety Appliance Act of 1893.

Correction: It would easy for Sheldon to ignore this fact when he is aboard a train that has been restored to its original design; internally and externally. He has been building toy models since he was a kid. He just wanted to know to what level this train has been restored.

XIII

The Terminator Decoupling - S2-E17

Corrected entry: On the train, the guys reference an eleven-hour train ride from Pasadena to San Diego, but it's only a 4 hour ride, at most.

00:10:00

Correction: The train was actually headed to San Francisco and made at least one stop when Summer Glau got off the train, since Pasadena is nearly 350 miles from San Francisco and it was not a nonstop route, the ride could take approximately eleven hours.

zendaddy621

The Friendship Algorithm - S2-E13

Corrected entry: When Sheldon was stuck in an infinite loop in his "friendship flowchart", Howard created an escape which he labeled "LDA"; however, Sheldon referred to it as "Least Objectionable Activity", which would be "LOA."

zendaddy621

Correction: It is easy for a D to look like an O.

kristenlouise3

Pilot - S1-E1

Corrected entry: At the end of this episode when Penny asks to use Leonard and Sheldon's bathroom for a shower, when she goes down the hallway towards the bathroom/bedrooms, she turns past the bathroom (the door that is visible from the living room) and turns right and goes towards the bedrooms.

Jack Adams

Correction: Penny could simply be going to grab a towel from the linen closet before having her shower.

kristenlouise3

The Adhesive Duck Deficiency - S3-E8

Corrected entry: There is no way Sheldon would have been able to hear Penny call him for help as as he did, through four closed doors, two rooms and a hallway.

luke f

Correction: Sheldon's 'Vulcan hearing' is an important plot device, used in a number of episodes for comic effect. This is one of them. In another episode, Leonard says he can hear her toilet flush, so the apartments clearly aren't very soundproof.

The Extract Obliteration - S6-E6

Corrected entry: Sheldon mentions that he scores a double letter score with a triple word score. On the Words with Friends board, this is impossible.

kristenlouise3

Correction: That is totally possible when you play on a random board, which has the bonus squares in different places. I have played it with an opening word point total of over 225.

The Raiders Minimization - S7-E4

Corrected entry: When Leonard and Penny are doing the 'business' at the university and Howard knocks on the door, Leonard opens and says "hey Si" (Howard's real name - Simon Helberg).

Correction: He says "Hey, sorry," while panting - he's apologising for taking so long to answer the door.

The White Asparagus Triangulation - S2-E9

Corrected entry: Sheldon obviously changes the relationship status on Leonard's Facebook page to 'in a relationship with Stephanie Barnett'. At this point it would have been impossible for Penny to see the status update, because it only shows up after both parties have confirmed it.

Tanngrisnir

Correction: You can see that a person is in a relationship before it is approved by the other person. It would simply say "[Name] is in a relationship" without the other person's name until it is approved, at which point it would say "[Name] is in a relationship with [other name]".

The Bat Jar Conjecture - S1-E13

Corrected entry: When the guys are practising for the Physics Bowl and they are sitting across from Penny, Leonard is sitting in Sheldon's seat, which Sheldon would never allow.

ashnzoe242

Correction: In most cases, this would be true. But given the way things were set up, he had to pick a new, temporary spot for the practice. It's likely that their living room setup is too complex to change just for a short amount of time, which is why the practice area was set up as it was. Sheldon chose a spot related to the practice area so he would be comfortable, just like he chose a new spot when the gang went to the north pole.

Knever

The Roommate Transmogrification - S4-E24

Corrected entry: Bernadette tells Howard that she chose the premature ejaculation project because neither of them has any heart diseases. However Howard has stated more than once that he has transient idiopathic arrhythmia. Also in the previous episode he actually emphasizes that his family has a history of heart diseases and alludes to a cave painting showing one of his ancestors clutching their chest.

Tanngrisnir

Correction: Transient idiopathic arrhythmia is not a disease, it is a disorder. They are different things.

The Justice League Recombination - S4-E11

Corrected entry: At the end of the episode, when Sheldon imagines going to the Grand Canyon to scream about Leonard, that's not the Grand Canyon, signs not withstanding. The location is Dead Horse Point State Park in Utah (near the town of Moab), with the view looking roughly south into Canyonlands National Park. [GPS near 38°28'12" by 109°44'30".] It's several hundred miles upriver from the Grand Canyon. [At least it is along the Colorado River.] The first national park sign looks authentic, but the small one at the overlook is fake, since that's not the Grand Canyon. And by the way, since it's just after New Year's, there would likely be snow at both the Grand Canyon and Dead Horse Point; the images used are not winter scenes.

Correction: But it's all occurring in Sheldon's mind. He does have an eidetic memory, but if he has never been to the Grand Canyon he can't remember it. He's imagining what it would look like if he were there.

Grumpy Scot

The Cushion Saturation - S2-E16

Corrected entry: At the end, Sheldon fires 5 shots at Leonard, who somehow ends up with 7 distinct paintball marks on his chest.

Jon Sandys Premium member

Correction: Paintball markers can easily fire two shots per trigger pull, especially when the CO2 in the tank is low.

Grumpy Scot

The Nerdvana Annihilation - S1-E14

Corrected entry: At the beginning, when Leonard has won the online auction, we see a shot of his laptop computer screen showing an Apple Safari browser window with Mac OS X window controls, but the laptop is a PC, not made by Apple. Mac OS X can only run on Mac hardware.

Correction: It is difficult but possible (and a TOS violation) to get Mac OS X to run on a PC. The company Psystar even did it commercially. Given Leonard and Sheldon's computer knowledge, it shouldn't be difficult at all. Or they could easily just be running a custom browser skin.

LorgSkyegon

The Zarnecki Incursion - S4-E19

Corrected entry: If Howard can hack into Blizzard's database so deeply that he can get the name and address of game players, he could easily restore all of Sheldon's stolen 'items'. Hacking personal details - a player's real identity and their home address! - is hardcore, detailed work that only an expert could do, compared to which adding a few extra items to a player in the game would be child's play.

Correction: Hacking the database to return items to Sheldon's account would also be traceable to Sheldon's account as cheating. That would get him permabanned if discovered, not a risk Sheldon wants to take.

LorgSkyegon

The Jiminy Conjecture - S3-E2

Corrected entry: Professor Crawley states he discovered a new species of dung beetle (named after him) in a rain forest in Borneo. That is impossible - dung beetles do not live in damp climates as the fecal matter upon which they live degrades too quickly when moist. You can find dung beetles in Savannah grassland, semi-arid desert, some lightly wooded areas, but a rain forest? Never.

Correction: Never is a big word. Deltochilum valgum and Oxysternon pteroderum are two examples of dung beetles that live in rainforests.

Corrected entry: Penny uses different mailboxes along the top row to get her mail.

terry s

Correction: My mailbox was changed three times in the three years I lived in my last apartment.

LorgSkyegon

The Codpiece Topology - S2-E2

Corrected entry: Sheldon's battery runs low during Leonard's date with Leslie so he gets an extension cord but leaves the door open. As he goes down the stairs the extension cord unwinds until he can't go any further and attempts to pull it. When Leonard gets up to shut the door there is no extension cord plugged into the outlet or leading out of the apartment.

lizbeth1fl

Correction: When Leonard gets up to shut the door, the camera doesn't pan low enough to see the outlet or the floor so there's no way to tell if the cord is plugged in or not.

Guy

Show generally

Corrected entry: Leonard and Sheldon live in 4A and Penny in 4B. Yet when they go to the mailbox downstairs, Sheldon's mailbox is the upper left one while Penny's is the third or fourth one from the left. Mail boxes have to be in apartment order, not necessarily for the tenant who could remember where their box is but for the mailman to be able to use the apartment number as to placement of the mailbox. Whenever a sub carrier would do the route, he wouldn't be able to follow the random pattern.

terry s

Correction: My first apartment building didn't have them in order. The boxes were marked with either the apartment number, the tenant names, or both.

LorgSkyegon

The Monster Isolation - S6-E17

Corrected entry: When Leonard tells Sheldon to hand over his Nintendo DS, Sheldon gives him a shiny aqua console. The Nintendo DS has never been produced in that color: the console is actually a 3DS, not a DS.

Moose Premium member

Correction: Semantics. To most people, "DS" is sufficient enough to specify all of the Nintendo DS consoles. The same way that "Xbox" is sufficient enough to specify the Xbox 360.

THGhost

The Robotic Manipulation - S4-E1

Corrected entry: In a conversation with Penny, Sheldon says "Progidy" instead of "prodigy". Definitely not a mistake he'd make.

00:19:50

ivanzel

Correction: Sheldon actually says "I suppose she will have to have access to our progeny".

THGhost

The Luminous Fish Effect - S1-E4

Corrected entry: At the buffet table when the gang gets food, Howard walks in with his 'date.' Between shots, as he walks in, in one shot Sheldon puts his right hand up on his plate. In the next shot his hand is down.

Hamster Premium member

Correction: I have just reviewed this scene. Sheldon makes only one movement with his right hand as Howard walks in. Between shots he was able to walk from behind the group to the side. This gives him ample time to move his right hand back down.

XIII

Show generally

Corrected entry: The design of the apartment is impossible. Penny's door is directly above the main exit door. We have seen the outside of the apartment and there is no overhang to accommodate all the apartments on the left side.

kristenlouise3

Correction: Not exactly true. Using scenes from S03E20 - The Spaghetti Catalyst as a reference. Penny's door is flush against the stairwell. Scenes from inside the building downstairs, shows the main door is a distance away from the stairwell (lets say 8-9 feet). During a scene from outside, we can see that there is an external part of the building outside. The outside wall of the plant trough is at least 6 feet away from the door. This equates to about 15 feet for the width of Penny's apartment.

XIII

Show generally

Corrected entry: In the opening song, one line is 'Autotrophs began to drool'. In fact, Autotrophs are self feeding organisms like plants, not animals, and so therefore cannot drool.

elephant2541

Correction: Autotrophs are in fact plants. Trees are the most common form of "plant". Trees seep. The Maple Leaf tree has been known to seep water, which, poetically, is drooling.

XIII

The Shiny Trinket Maneuver - S5-E12

Corrected entry: In 3-14 "The Einstein Approximation" Bernadette stated that she is able to easily handle children as her Mother ran an illegal day care centre in their basement. However, in this episode she states that she hates children because her mother worked and she had to bring up her siblings, and she cannot properly react to children. So which is it? Can't be both.

Correction: In 3-14 she says she can handle "stubborn children" and in 5-12 she refers to "little kids". Every parent will tell you there is a big difference in behavior in children at child-care age [i. e. Daycare children] and little kids [a little older]. It is easier to get them to do things when they are small but once they develop their "attitudes", it is very hard to get them to do what you want.

XIII

The Peanut Reaction - S1-E16

Corrected entry: At the apartment, after pretending to eat some of the granola bar, Howard throws the bar and wrapper down on the coffee table. He does not pick it up again before they leave the apartment. Later, at the hospital, he takes the bar from his pocket and eats some.

pinkwafer

Correction: No, he breaks a chunk off the bar and stuffs it in his back pocket so it would look like he took a bite. This is what he removes at the hospital.

Grumpy Scot

The Cruciferous Vegetable Amplification - S4-E2

Corrected entry: When Leonard announces how much the guys owe him for their part of the pizza, he says "it came to $28.17, let's say 6 bucks apiece". It should be 7 bucks apiece.

Correction: The four of them plus Penny is 5 people. It is closer to $6 each.

XIII

The Stag Convergence - S5-E22

Corrected entry: Leonard and Penny are inhaling Sulphur Hexaflouride to make their voices low. The effect can be seen to be fake for two reasons. First, their voices go back to normal instantly and on demand - the gas actually takes a while to clear. Second, when Leonard releases the balloon, it flies away; it should just fall to the floor because Sulphur Hexaflouride is heavier than air.

Moose Premium member

Correction: 1. Wrong episode. This scene is from Episode 23. 2. Your voice will clear in as much time as it takes to clear your lungs - one or two breaths. 3. A sulfur hexafluoride balloon will still fly, as the escaping gas is still propelling it, as demonstrated in this clip by Mythbuster Adam Savage http://www.youtube.com/watch?v=d-XbjFn3aqE.

LorgSkyegon

The Zarnecki Incursion - S4-E19

Corrected entry: When the characters are driving in the car duringthis episode, it looks to be a black car (when they film in front of the car). When they run out of gas, there is a shot of them pulling over. The problem is, the car is white when pulling over.

*BleuFever

Correction: There are several episodes where Leonard's car is visible in daylight and it has always been a dark silver color. When viewing that car in low light it would appear to be black. Later when Leonard pulls the car over it is not white, it is silver.

The Tangerine Factor - S1-E17

Corrected entry: When Penny and Leonard are talking to Sheldon about their date, Sheldon refers to Schrodinger's Cat, stating "The cat in the box is both alive and dead, until you open the box and find out." Yet the precise point of the Schrodinger's Cat example is that the cat cannot be both alive and dead. Schrodinger was arguing against physicists of the time who claimed that certain subatomic particles were special and could be in opposite states at the same time; his argument was that you can't make small systems special because a large and obvious system (e.g., the cat) could always be made to depend on the state of the smaller one, and for a large and obvious system to be in opposite states simultaneously is ridiculous. Now, this is pretty obscure and the misunderstanding of Schrodinger's Cat experiment is widespread, but this is Sheldon we're talking about.

Moose Premium member

Correction: This is not a factual error on Sheldon's part. He explicitly says that Schrodinger's experiment was an attempt to explain the Copenhagen interpretation of quantum physics, which implies that the cat could be both dead and alive until the box is opened and observed. While he doesn't explain that the point of the experiment was to critique the prevailing thought of the time, his overall point to Penny fits within the context as given.

The Nerdvana Annihilation - S1-E14

Corrected entry: When Leonard starts packing his action figures away, the box says "Leonard's collectables. The spelling should be "collectibles" - an unlikely mistake from someone of Leonard's intellect.

Fat Tony69

Correction: Both spellings are correct. I checked thirty six online dictionaries and they all list "collectable" and "collectible" as the correct spelling.

The Cushion Saturation - S2-E16

Corrected entry: At the end of the episode, Sheldon shoots Leonard five times, but there are six stains on Leonard's armor.

Brad Premium member

Correction: Paintball markers can easily shoot two balls in one shot. They aren't as reliable as a real gun.

Grumpy Scot

The Transporter Malfunction - S5-E20

Corrected entry: During their discussion about the guest list for Howard's wedding, Raj speaks openly, not only in front of Penny, but sitting next to her. They haven't been drinking.

Correction: This scene opens with Raj with a drink in his hands. Yes! he has been drinking.

XIII

Pilot - S1-E1

Corrected entry: When Howard is showing Penny the online game and Penny expresses interest, Raj says "Smooth", even though Penny is right there - breaking his mutism rule.

Moose Premium member

Correction: This has never been a diagnosed condition in his case. In Episode 13 of the same season, during a group conversation he accidentally says "good story" with Penny present and immediately realized that he talked in front of a female then covered his mouth. This is just a individual non-medical problem.

XIII

The Shiny Trinket Maneuver - S5-E12

Corrected entry: After Amy stalks off on Sheldon, Penny tells him off because she told him some good news about her paper being published, and he belittled her achievements while bigging up his own, trivial activities. She is very specific about what he did and why Amy reacted. How did she know all of this? She was nowhere near the table at the time and could not possibly have overheard their conversation. She might assume Amy is mad at Sheldon but she can't possibly know why.

Correction: Penny is behind them cleaning a table and you actually see her overhear what they are talking about.

Anastasios Anastasatos Premium member

Show generally

Corrected entry: Though mentioned many times, no Marvel Comics are seen on the shelves of the comic book store.

MasterOfAll

Correction: There ARE Marvel comics shown on the shelves sometimes, most notable during Season 3's "The Psychic Vortex" aka the episode with Stan Lee in it.

SexyIrishLeprechaun

The Agreement Dissection - S4-E21

Corrected entry: For an obsessive genius Sheldon makes a stupid mistake when he blackmails Leonard into signing a new roommate agreement - any contract signed under duress is invalid. He gains nothing from Leonard signing the new agreement as no other action on his part is required. Effectively Sheldon has got his autograph. Big deal. Leonard is free to ignore the new agreement if he feels like it - and his lawyer was there to witness the fact that he was forced against his will to sign in the first place. This also begs the question of why Priya gets in such a panic about Sheldon blackmailing Leonard by threatening to reveal details of their relationship to her parents - why didn't she just advise Leonard to sign on the dotted line, explaining later that he signed an invalid contract? It would certainly have saved her a lot of grief.

Correction: Priya might have brought the idea of the letter of the law in, but Sheldon has never actually sued anyone for violating the roommate agreement. Leonard abides by it because otherwise Sheldon will become unliveable with. Priya won't give Leonard any more advice because of the risk that Sheldon will tell Priya's parents about Leonard's relationship.

Moose Premium member

The Classified Materials Turbulence - S2-E22

Corrected entry: Why would all the astronauts want to do something as dangerous as a spacewalk, particularly one that not only leaves nobody in the International Space Station, but one that has been forbidden by NASA? Because of the smell of waste leaking from the defective toilet? If they can still smell that after they have put on their spacesuits, they are in a lot more trouble than they think. There is no need to leave the station, and they would never, ever do something as stupid as all leaving the ISS at the same time anyway. Besides, do they think the problem of the leaking toilet is going to fix itself while they are all out spacewalking?

Correction: They never say anything about a smell. We can only assume a worst case-scenario, which in this case, would be their feces floating around inside the station. Of course, even something like this wouldn't put real astronauts outside, but since it's a TV show, it falls into the suspension of belief category.

Knever

Correction: If you can explain away technical errors like this by claiming 'suspension of disbelief' that about half of this site just became redundant. There is a definite error in the episode, identified in this posting : there would never, ever be an occasion where every astronaut would leave the ISS at the same time.

The Robotic Manipulation - S4-E1

Corrected entry: Howard explains the ease with which he "borrowed" the programmable robot arm thus : "You just have to take it out to your car as if you own it". Howard doesn't have a car - he has a Vespa scooter, and there is no way he could carry the robot arm on that. (While we are on the subject, how does he transport it from Sheldon and Leonard's apartment to his house?).

Correction: His mother very likely has a car (we've heard her say that she's driving back to the grocery store), which Howard very likely used for this occasion.

Knever

The Financial Permeability - S2-E14

Corrected entry: In 'Pilot' (season 1, episode 1), Leonard and Sheldon attempt to sell their sperm for money to install a T1 line in their apartment, and in 'The Dumpling Paradox' (season 1, episode 7), Sheldon says to Leonard "Frankly, if I could afford the rent, I would ask you to leave". Yet in this episode he says to Penny, "My expenses account for 46.9% of my after-tax income". The only way that his expenses could account for less than half his income just over a year after these lines can only really be explained away if the university gave him a pay rise of over 100%, which is incredibly unlikely for many reasons.

Douglasac

Correction: There are so many possible situations that could explain all of this. Regarding his payrise, You said "unlikely" but that does not mean impossible. That aside, Sheldon could have changed his spending/expense habits. Personally, I did when I got a payrise, regardless of how much it was. Also Sheldon has also proven to us that he is capable of making sarcastic comments now and then whether he is aware he is doing it or not.

XIII

The Loobenfeld Decay - S1-E10

Corrected entry: In "The Loobenfield Decay" Sheldon and Leonard go to absurd lengths to avoid having to hear Penny perform because her singing voice is so horrible. But in series 2 episode 18 "The Work Song Nanocluster", series 3 episode 3 "The Gothowitz Deviation" and series 3 episode 8 "The Adhesive Duck Deficiency" (amongst others) she is shown to have a strong, pleasant singing voice, and she sings in front of both men without them objecting. They aren't just being polite - they genuinely like her singing. So, which is it?

Correction: If either of those episodes occurred before "The Loobenfield Decay" episode than this could be a valid plot hole BUT they all occur after. It is fair to conclude that she got better.

XIII

The Staircase Implementation - S3-E22

Corrected entry: When Sheldon tells Leonard about the time travel clause, he states "in precisely five seconds." Anybody who knows anything about time travel know that you need a definitive point in time, so without having that exact date and time written down somewhere, there's no way a future version of them could arrive at that unspecified time. Sheldon's too anal to ignore something like that.

Knever

Correction: The precise time would be slightly before the signing of the Roommate Agreement, which is about to happen, so it's a markable point in their histories/future histories.

Captain Defenestrator Premium member

The Cruciferous Vegetable Amplification - S4-E2

Corrected entry: When Sheldon is taking his Apple II to be signed by Steve Wozniak, the machine he's taking clearly has a monitor attached in place on the top. The Apple II did not have an attached monitor.

Moose Premium member

Correction: You can clearly see a gap between monitor and main computer unit, indicating that they are separate units. Also the colors are different, further indicating they were made separately.

XIII

The Wiggly Finger Catalyst - S5-E4

Corrected entry: In this episode, everyone is surprised to learn that Raj's family is enormously rich, but in episode 15 of season 4 Raj states that his family is wealthy and has lots of servants.

Correction: They knew Raj's father was a well-off doctor, so someone we might call upper class. This episode they found out he was extremely rich, more along the lines of the richest men in the country.

LorgSkyegon

The Luminous Fish Effect - S1-E4

Corrected entry: When Penny and Sheldon are driving to the supermarket, Sheldon is explaining the weight of the car and how it affects her braking time. He estimates the car's weight to be 4000 pounds, 140 for himself and 120 for Penny, and then rounds the total up to be 4400 pounds, when it actually should be 4260. It's extremely out of character for somebody like Sheldon to make such a basic addition mistake.

LittleWildman

Correction: Or he could be including other things he just failed to mention, such as the contents of the vehicle and trunk.

LorgSkyegon

The Toast Derivation - S4-E17

Corrected entry: Sheldon makes fun of Leonard's idea to go to Raj's for dinner by speculating that they could stop using the letter M, which would be "isguided and oronic. Later he says that "This is adness. Complete and utter adness. He should have said "This is adness. Coplete and utter adness., leaving the M out of the word "complete" - and there is no way a pedantic, obsessive genius like Sheldon would make a mistake like that.

Correction: I viewed this scene more than 10 times and listened closely and Sheldon says, "This is adness; this is utter and coplete adness. He does in fact take the "m" out of the word complete.

The Dumpling Paradox - S1-E7

Corrected entry: Sheldon states that reductio ad absurdum is "the logical fallacy of extending an argument to a ridiculous extreme and then challenging it". This is incorrect; this is the straw man fallacy. Reductio ad absurdum is the entirely valid inferential technique of demonstrating that the consequences of an argument being true result in a contradiction.

Moose Premium member

Correction: Sheldon is correct. "Reductio ad absurdum" (Latin: "reduction to the absurd") is a form of argument in which a proposition is disproven by following its implications logically to an absurd consequence. Proof by contradiction is a specific form of Reductio ad absurdum. http://en.wikipedia.org/wiki/Reductio_ad_absurdumA strawman argument is committed when a person simply ignores a person's actual position and substitutes a distorted, exaggerated or misrepresented version of that position.http://www.nizkor.org/features/fallacies/straw-man.html The major difference between the two is that an Reductio ad absurdum argument presents the opponent's claim correctly but carries it to an extreme. The Strawman argument presents the opponent's claim incorrectly.

Guy

The Adhesive Duck Deficiency - S3-E8

Corrected entry: When Penny and Sheldon get into the car to drive to the hospital, she makes the remark, "You do have a learner's permit, right?" He answers yes and explains he has logged several simulation hours which ended badly. She already knows he has a learner's permit and about the simulations, since in season 2, "The Euclid Alternative," she was with him at the DMV when he got the permit and stood beside him during the simulation, actually hitting him in the face with a pillow to mimic an airbag when he crashed.

lizbeth1fl

Correction: Actually, after Sheldon said that it was the first time driving an actual vehicle, she said "you do have 'your' learners permit, right?" It was an indirect reference to the fact that (approx) a year had passed (a season for us viewers) and he had not stepped into an actual vehicle. Penny has been known to be sarcastic from time to time.

XIII

The Killer Robot Instability - S2-E12

Corrected entry: Kripke states that there is no guarantee that he will face Leonard, Sheldon, and Raj in the round-robin. In a round-robin, all competitors face each other in turn. It is out of character for Kripke not to be aware of this, and especially for Sheldon to not correct someone making this basic mistake.

Correction: Although the tournament is scheduled as a round robin, it's apparent that a losing robot may be actually destroyed and unable to compete further. MONTE would be unable to face Kripke's robot if it was destroyed in a previous match, regardless of whether it was scheduled to meet them or not.

The Creepy Candy Coating Corollary - S3-E5

Corrected entry: Wil Wheaton tells Sheldon that he missed the convention because his grandmother died. When Wheaton later refers to a living grandmother, Sheldon realizes he has been tricked. He shouldn't - presumably Wheaton, like everyone else, has two grandmothers (mother's and father's side) and thus Wheaton announcing he has a living grandmother in no way contradicts what he said before. This alone shouldn't tip Sheldon off that Wheaton was lying.

Correction: In context of how the scenes played out, it is directly implied (and very obvious) that Wheaton is talking about the same grandmother.

The Excelsior Acquisition - S3-E16

Corrected entry: Penny got a red light camera ticket while Sheldon was driving her car. She says she gave up Sheldon as the driver to the court because she didn't want to get any more points on her license. You don't get points on your license for a camera issued violation. The registered owner just gets a straight fine. A police officer has to issue a ticket at the scene to get license points.

Correction: Penny is not a legal expert. She might not be aware of this technicality and is still afraid of losing points.

Show generally

Corrected entry: In the episodes "The Dumplings Paradox" and "The Pirate Solution" Penny mentions that she has a brother. But in the episode "The Maternal Capacitance", Penny talks to Leonard's mother about how her father had always wanted a boy.

Space_Cowgrrl

Correction: She has a younger brother. Her father treated her like a boy because the male had not been born yet. And apparently, he kept treating her like a boy.

Pilot - S1-E1

Corrected entry: Raj talks aloud whilst Penny is still in the room.

kateykatek

Correction: Raj enters the room while Penny is in the bathroom about to take a shower. Raj does talk but, doesn't yet know she's there.

The Spaghetti Catalyst - S3-E20

Corrected entry: When Sheldon says goodbye to Howard after walking with him on the street, he says "BYE, SHEL" instead of "BYE, HOWARD".

Rays2011

Correction: Howard tells Sheldon to have a nice walk and Sheldon replies "I shall", not "Bye Shel".

The Love Car Displacement - S4-E13

Corrected entry: At the end of the show Sheldon states on the walkie-talkie, "I spy with my little eye, a ferrous metal," Later he reveals that what he spied was the aluminum rims of a police car. Aluminum is a non-ferrous metal - definitely not a mistake Sheldon would make.

allensis

Correction: Sheldon does say a non-ferrous metal.

The Vengeance Formulation - S3-E9

Corrected entry: Kripke pumps helium into Sheldon's office to make his voice squeaky while conducting a phone interview. However, the helium is pumped in via a tube that is above the height of Sheldon's head, and helium floats in air; therefore, the helium would have accumulated near the ceiling and would not have affected Sheldon within a couple of minutes as shown.

DavidK93

Correction: Kripky opens 2 massive canisters of helium - enough to accumulate low enough to affect Sheldon's voice.

The Friendship Algorithm - S2-E13

Corrected entry: Sheldon asks at the book store information desk if they have any books about making friends, and the employee tells him that all their books like that are for "little kids." It is unreasonable that the employee would not have been able to tell Sheldon about the very well known self-help book "How to Win Friends and Influence People," if Sheldon had not already been able to discover it through a cursory internet search.

DavidK93

Correction: 1. They didn't stock the book. 2. The book was published in 1936. She hadn't heard of it herself. 3. Sheldon only thought of a 'How To make Friends' book after he entered the shop, so the idea of looking up a seventy year old book on the internet is irrelevant.

The Bat Jar Conjecture - S1-E13

Corrected entry: Towards the end of this episode, Raj answers a question by buzzing in with Leslie Winkle sat next to him, and he answers. I though he couldn't talk to women or around women? Is this a mistake?

Nameless

Correction: This point is addressed earlier in that episode. Leonard explains that he can talk once they're all mingled in with males (as in the audience).

The Precious Fragmentation - S3-E17

Corrected entry: The "ring" prop is alleged to be one used in "The Lord of the Rings" movies. However, the prop used in the TV show has a gold chain, but in the films Frodo's ring is held on a silver chain.

woodrz

Correction: The chain isn't what's important. It's the ring. The chain is not part of the prop.

The Hamburger Postulate - S1-E5

Corrected entry: When Leonard is explaining his thoughts to Sheldon, during the rant which includes him naming who he intends with the words she or her (eg "She: Penny, Her: Leslie), he states, "Indicating that She: Penny had no interest in me asking Her: Penny out," which makes no sense.

DrEvilGenius

Correction: Lenord is confused and ranting so making a mistake in that situation is not unlikely.

Show generally

Corrected entry: Throughout the series Penny complains that she is broke, and is paid minimum wage at The Cheesecake Factory. She even takes on additional duties as a barmaid to try to earn extra money. We also learn that Sheldon and Leonard live together as their apartment is too expensive for one person - Sheldon says he would be happy to live alone if he 'could afford the rent'. Penny's apartment is almost identical to theirs - it can't be that much cheaper. So, if two University lecturers can't afford an apartment in that building, how on earth can a waitress on minimum wage do so?

Correction: Penny complains that she is broke, but that is probably due to having to pay the rent, leaving her little money after. Penny does a lot of work to scrape up rent money and obviously she is able to earn the sufficient amount to afford it. Sheldon and Leonard work at the university, but as it is stated they earn limited amounts. Also, Sheldon and Leonard have a two bedroom apartment while Penny probably has a one bedroom apartment and therefore would not pay as much.
