The Big Bang Theory

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.

The Platonic Permutation - S9-E9

Continuity mistake: In episode 16 of season 1, Penny is talking about making a cake for Leonard's birthday and states she knows his birthday because she was checking a horoscope for him. But in this episode she does not know when his birthday is, which leads to Leonard revealing he was secretly reading Penny's diary. (00:40:00)

Suggested correction: It's certainly possible to forget something you knew eight years ago.

LorgSkyegon

This is perhaps true for two people who rarely have contact, but I would list this as a character mistake. Penny and Leonard are in a serious relationship and are married at this point.

Bishop73

I forgot my wife's birthday on a number of occasions. It's one of the reasons she is now my ex-wife.

There's a difference between forgetting and not knowing.

Bishop73

This is also a couple who BOTH forgot it was their anniversary.

LorgSkyegon

Suggested correction: She knew his birthday because she had very recently checked his horoscope. It is more than possible for someone to forget the birthday of a friend, even if you know vaguely when in the year their birthday is.

But they're more than friends. They're in a relationship and married at this point.

Revealing mistake: Most of the time, though not all the time, Leonard has no lenses in his glasses.

The Rhinitis Revelation - S5-E6

Other mistake: When Mary is rubbing VapoRub on Sheldon's chest, she makes a comment that last time she saw that there was no hair, to which Sheldon replies "Yeah it filled in last year." In Season 1, Episode 11, Penny rubs VapoRub on Sheldon's chest and a very clear remark about chest hair was made. Season 1 for the show was 4 years ago.

Suggested correction: Sheldon is probably joking when he tells Mary his chest hair filled in the previous year.

Sheldon doesn't make jokes.

Ssiscool Premium member

He doesn't understand sarcasm, hence, doesn't know when to be sarcastic.

ckbyers

If Sheldon didn't make jokes, the term "Bazinga" would have never came into play. Ever.

ckbyers

And nearly all instances of Bazinga are not used in a funny circumstance. Indicating poor judgement and lack of knowledge regarding jokes.

Ssiscool Premium member

They were funny to him. And to the audience.

lionhead

Google "how many times has Sheldon said "Bazinga" " - and it'll explain that he does, indeed - joke.

The Benefactor Factor - S4-E15

Continuity mistake: When Sheldon and Leonard are in the kitchen discussing Leonard's upcoming night out with Mrs. Latham, there's a plastic bottle of orange juice on the table that keeps disappearing and reappearing as the camera switches between Sheldon and Leonard.

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

Suggested correction: The bottle is there every time, a few times because of the camera angle it is hidden by Sheldon.

Bowling255 Premium member

The bottle of OJ is right next to a container of Coffee Mate, both items always visible when the bottle of OJ is present. When the OJ is not present, only the Coffee Mate is there, near enough the center of the table to not possibly be blocked out by either Sheldon nor Leonard.

No it is not right next to the coffee Mate, there is some distance with a phone in between. You can sometimes see the bottle behind Sheldon when he moves.

The Hamburger Postulate - S1-E5

Character mistake: When Sheldon knocks on Penny's door to seek advice about the tie on Leonard's doorknob, he does not use his typical triple knock. (00:07:43)

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

Suggested correction: Sheldon doesn't develop this trait until S2 E18.

Ssiscool Premium member

That I beleive is the first episode with the triple knock.

Ssiscool Premium member

First time he knocks 3 times is in Episode 2 of Season 1. First time knocking 3 times followed by saying the name is episode 10 of Season 1. The ritual of 3 knocks and 3 times saying the name and then stopping is Episode 5 of season 2.

lionhead

My mistake. It's been several years since I've seen the early seasons. I was going off memory.

Ssiscool Premium member

Suggested correction: A one-time lapse in someone's usual behavior does not count as a "character mistake", even in the case of someone given to ritualistic behavior as Sheldon is.

zendaddy621

Ah, but in an episode he explains he had developed this particular ritual at age 13 after walking into his parent's bedroom without knocking and seeing his father having sex with another woman. He says he started knocking 3 times since then and would never forget. So its not consistent and a mistake as this is not the only example one can name.

Season 1 generally

Continuity mistake: In "The Luminous Fish Effect" (S1E04) Sheldon tells Penny he weighs 140 pounds. In "The Porkchop Indeterminacy" (S1E16), he tells his sister he weighs 165. 25lbs difference would be a noticeable change, but he looks the same.

Suggested correction: Lying to Penny but not to his sister, not inconsistent with the characters and his relationships.

LordKelvin

There's been several episodes showing Sheldon is not a good liar.

The Closure Alternative - S6-E21

Continuity mistake: Sheldon and Amy are talking while drinking tea together. The entire time, Sheldon has his hand next to his other hand, but in an individual shot, his hand is suddenly on his other wrist.

Suggested correction: There is a moment when he puts his hand there. So nothing wrong here.

The Beta Test Initiation - S5-E14

Character mistake: Sheldon says (during Fun With Flags) "But like the flag over Fort Sumter, I'm still here." The Sumter flag was lowered when the fort surrendered to the Confederates. The flag over Fort McHenry was never taken down despite the British bombardment and inspired Francis Scott Key to write the National Anthem about it. Whouldn't a vexologist know that?

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

Suggested correction: Sheldon is referring to the actual Fort Sumter flag, which still exists and is on display at the Fort Sumter museum.

LorgSkyegon

Sheldon is not referring the actual flag (especially since if the actual flag is in a museum it's not still over Fort Sumter). Sheldon is referencing the line from The Star-Spangled Banner "our flag was still there." Key wrote The Star-Spangled Banner after seeing the flag over Fort McHenry was still there. The writers simply made a mistake and Sheldon the character would know which flag inspired the line. Incidentally, the actual Fort McHenry flag also still exists.

The Creepy Candy Coating Corollary - S3-E5

Continuity mistake: Bernadette speaks regular here. In future episodes she suddenly has a higher-pitched voice.

Suggested correction: This isn't really so much a mistake as it was a character tweaking, which happens often in TV series.

The Vengeance Formulation - S3-E9

Factual error: The foam Sheldon used on Kripke consists of mixing ordinary dish soap, hydrogen peroxide, and saturated potassium iodide. That kind of exothermic reaction is dangerously flammable, so it should have severely burned Kripke and the members of the university board when it fell on them.

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

New this month Suggested correction: Correct, but I think you're confusing 'flammable' with hot. Without a source of ignition, the flammable foam would not ignite and generate heat from combustion. However, this reaction is sufficiently exothermic that the falling goop would not have had time to cool, and would likely have burned the individuals underneath. You can see this during the test in the apartment when the reaction generates copious clouds of steam.

Show generally

Continuity mistake: In the early episodes, Leonard is depressed and buys cat stuff. He comments that he has taken in to account Sheldon's asthma with a hyper allergenic cat. Later in the series it is Leonard with asthma and Sheldon who gets all the cats.

Suggested correction: Presumably Sheldon also buys non-allergenic cats.

LordKelvin

And Sheldon is shown to have no courtesy or thought for other people.

The Big Bran Hypothesis - S1-E2

Other mistake: Leonard is awoken by the apartment door closing. When he walks into the living room the door is open. (00:08:55)

Ssiscool Premium member
Upvote valid corrections to help move entries into the corrections section.

Suggested correction: He's awoken by a door closing, not necessarily the front door. He could have heard Sheldon closing his door.

Bishop73

While that is possible, it is unlikely as it's clear Sheldon has already made a dent in the cleaning of Penny's apartment. Plus Sheldon would have simply replied to Leonard when he called out.

Ssiscool Premium member

Show generally

Continuity mistake: In the beginning of the series Sheldon knocks on Penny's door only once. Later in the series Sheldon explains he has always knocked 3 times because he walked in on his father with another woman.

Suggested correction: Sheldon goes through phases of his mannerisms. This is pointed out a few times across the show.

The Countdown Reflection - S5-E24

Factual error: There is not a snowball's chance of Howard becoming an astronaut. He suffers from cardiac arrhythmia, something about which he is completely open. "Transient" or not 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. Note also that during his basic training he shows signs of severe stress and trauma which would inevitably trigger a cardiac episode. Even if it didn't the fact that he was falling apart at the seams would have him removed from the programme for his own good.

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.
