The Big Bang Theory

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.

Ssiscool

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

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.

Ssiscool

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 lands on them. 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

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.

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

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 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

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

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

kristenlouise3

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

They ate there almost every episode.

terry s

They ate there every Tuesday and Sheldon always got the same thing (except when following the dice), the barbecue bacon cheeseburger with the barbecue sauce, bacon and cheese on the side.

Bishop73

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

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.

Knever

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.

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.

Captain Defenestrator

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

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

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

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]".

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

Grumpy Scot

The Pork Chop Indeterminacy - S1-E15

Character mistake: In his conversation with Missy Sheldon makes it clear that his superior intelligence is a result of a random, mutated gene. Since Missy isn't similarly intelligent she obviously isn't carrying this mutated gene (which would be a billion to one shot anyway) so her offspring wouldn't inherit it. Sheldon would know this - his offspring would carry the mutated gene for superior intelligence, Missy's would not. Anyone knowing enough about genetics to use the term 'randomly mutated gene' understands enough to know that the mutated gene would only be expressed in a direct line from the carrier - Sheldon. Also bear in mind he has a model of the DNA molecule in his living room - it is obviously an interest.

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: Genes can be dormant. Which allows them to skip generations. Therefor Missy's children could actually get the "mutated" gene. This is especially true since Sheldon and Missy are twins. Also, since the episode is about who out of Leonard, Howard or Raj, Sheldon would allow to "mate" with his sister, there is the added "insurance" of getting any smart genes from any of the 3 Lothario's mentioned above.

If you are going to try to argue with a geneticist about genetics, please use the correct terms. Sheldon is not referring to a recessive gene - there is no such thing as a dormant gene - he is speaking of a randomly mutated gene. Those are the words he used. If he had inherited a homozygous recessive karotype - one recessive gene from each of his parents - then somewhere in his family tree there would similarly gifted people, in which case he would use the correct term - a recessive gene. If Missy is a heterozygotic dominant karotype possessing the recessive gene for super-genius and the dominant for ordinary intelligence then mating her with Howard, Raj or Leonard would be a waste of time as their dominant genius gene would prevent the recessive super-genius gene from being expressed in the phenotype of the resulting child. The child would be highly intelligent but not on Sheldon's standards. It doesn't matter if Sheldon does not know any of this as he refers several times to a randomly mutated gene, not a recessive one. Missy does not carry the super-genius gene. The posting is correct.

Sheldon is prone to magical thinking when necessary to preserve his obsessive need to control his environment. He may have simply ignored the flaw in his reasoning, as even the most intelligent humans do when venturing outside their ares of expertise. He may be interested in the science of genetics, but his Ph.D. in physics doesn't qualify him as an expert in that field.

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

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