The Big Bang Theory

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.

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.

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

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

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.

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 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.

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.

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

Ssiscool

Correction: Suspension of disbelief has to play a part here. Actors are allowed to play other roles, and being many years later, Sean Astin looks quite different, so even if there was a meta element of "this person looks like the actor who played Sam", Sheldon wouldn't necessarily even notice the similarity.

Correction: I'm not sure if this is meant to be a troll entry or a joke. Sean Astin doesn't play himself in this episode, he plays Dr. Pemberton.

Bishop73

Correction: He also may have gotten the idea for doing magic to get girls to his room, but actually started doing it to cheer up his mother.

LorgSkyegon

Correction: And Wolowitz is known to exaggerate the truth.

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

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 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: 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.

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.

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 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.

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 Holographic Excitation - S6-E5

Trivia: In this episode, Sheldon and Amy are trying to decide on couples' themed Halloween costumes. Sheldon is standing in front of the dry erase board. There are 2 columns written on the board. One named "Couples I Like" and the other "Couples You Like." Under the "Couples You Like" column, one of the couples is Blossom and Joey. Blossom is the name of the television character played by Mayim Bialik in the 90s and Joey was one of her brothers.

Chosen answer: The song is called "Dark as a Dungeon" and was written and first performed by singer-songwriter Merle Travis in 1946. It has been performed by a wide array of artists, including Tennessee Ernie Ford, Harry Belafonte, Dolly Parton, Queens of the Stone Age, Kathy Mattea and Amy Grant. But it was made most famous when it was performed and recorded by Johnny Cash during his concert at Folsom Prison in 1968. According to Wikipedia: "It is a lament about the danger and drudgery of being a coal miner in an Appalachian shaft mine. It has become a rallying song among miners seeking improved working conditions."
