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 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.

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.

The Long Distance Dissonance - S10-E24

Corrected entry: Dr. Ramona Nowitzki returns and Sheldon introduces her to everyone as if they have never met her but, outside of Amy and Bernadette, they did years ago back in season 2. At the very least Leonard and Penny should remember her. But no-one acts like they do.

luke f

Correction: When bringing her to lunch with the other guys, Sheldon specifically says "You may remember Dr. Nowitski" and they reply. They obviously do remember meeting her.

Correction: As the other correction states he introduces her by saying you may remember. Sheldon is also very literal and skeptical of Penny's memory, having had to explain most things for a decade.

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.

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.

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.

What about Hawaii?

Honolulu, HI has an Interstate Highway. Not all Interstate Highways physically go from one state to another, the name just indicates it receives federal funding as part of the National System of Interstate and Defense Highways initially set up through the Federal Aid Highway Act.

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 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.

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.

Correction: She's just making a joke.

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.

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.

Moose Premium member

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.

terry s

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

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 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 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 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 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.

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.

Ssiscool 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.

2

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 Habitation Configuration - S6-E7

Continuity mistake: When Howard is almost done moving out of his mother's house, there is a table in front of him with a measuring device in the top corner. In one shot, the device moves to the opposite corner of the table. In a few shots later, the item returns to its original position.

The Euclid Alternative - S2-E5

Question: Though it comes up in other episodes as well, this one is focused on Sheldon needing a ride everywhere he goes because he can't drive, not to mention his not being welcome on the bus. Of course, this story element would be nonexistent if there was a simple answer, but it does beg the question: Does Pasadena not have taxicabs?

MFWills

Chosen answer: It does. The variable cleanliness of the cab and the habit of taxi drivers to engage customers in small talk would be too much for Sheldon to handle, and not an option for him.

Captain Defenestrator Premium member

Answer: Sheldon DID finally use a taxi when going to the airport to see and propose to Amy in New Jersey.
