The Big Bang Theory

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.

Correction: It wouldn't matter if they had. They hopelessly contaminated the sterile room by opening a window to allow the bird in in the first place. The bigger mistake is that some idiot allowed an unsealed window that could be opened in a sterile room in the first place.

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.

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

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.

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

The Vengeance Formulation - S3-E9

Corrected entry: 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.

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.

Correction: He never specified his level of proficiency. By saying he never learned it, he may simply be saying he's not fluent in it. He knows some basic words/phrases and that's it and saying he "never learned it" is simply that he never completed education in the language beyond the basic level.

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 Vengeance Formulation - S3-E9

Corrected entry: Sheldon caused thousands of dollars of damage to university property when he exacted his revenge against Barry Kripke in an act of blatant vandalism. Not only does he get Barry, but also the university president and other dignitaries. Sheldon would have certainly faced a disciplinary hearing, along with paying for the damages he admitted to causing. But nothing of the event is mentioned after that.

Mike Lynch

Correction: Nothing about it is mentioned in the show. Doesn't mean that he wasn't punished. He's lucky he held his job, probably. That's all we know.

The Agreement Dissection - S4-E21

Corrected entry: Amy has a monkey in her apartment smoking a cigarette for a study. At one point, he asks for another cigarette. Amy gives him one and walks away without lighting it, but a few seconds later, he's puffing smoke.

MovieFan612

Correction: Watch closely, while she's talking to Sheldon, you see her lean and light the cigarette. There is also an occasion where she gives the monkey a cigarette but comments on not lighting it.

Ssiscool

The Robotic Manipulation - S4-E1

Corrected entry: While driving towards the restaurant, Amy mentions she uses dandruff shampoo for her "dry" scalp. Dandruff and dry scalp have the same main symptoms, which are falling flakes and an itchy scalp, but they are two different conditions. In dry scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed. Therefore dandruff shampoo should be used for an oily scalp, not a dry scalp. (00:11:19)

Correction: Except there are dandruff shampoos that specifically treat dry scalp. In addition, dry scalp is commonly caused by dandruff.

Bishop73

More of a continuity error regarding this is that much later she claims that lice isn't attracted to her hair cos of her naturally oily scalp (contradictory).

Then that should be entered as a mistake. What was entered isn't a mistake.

The Codpiece Topology - S2-E2

Corrected entry: Sheldon states that the "Reinheitsgebot" would have severely limited the availability of mead in 1487. This is wrong for two reasons, the first being that the most commonly known version of this law wasn't introduced until 1516 and secondly this law only defined the price and the ingredients of beer and had therefore nothing to do with other alcoholic beverages like mead. (00:00:20)

Tanngrisnir

Correction: Purity Law or "Reinheitsgebot" was actually introduced in 1487, the Bavarian Law replaced this in 1516. In addition, the law was in effect on the production of beers in the broad sense of the word, it's main purpose was to reduce the need for "precious' resources like grain wheat and rye and also reduce the usage of 'pagan' plants and materials. In addition, the existence of law only effective on beers would suggest that mead was indeed not likely highly available.

The Big Bran Hypothesis - S1-E2

Corrected entry: Sheldon is wrong about the physics of pushing the furniture up the stairs. This is not just a question of work (energy) but also of power (energy/time). Since he and Leonard cannot produce an unlimited amount of energy per second, they may need to push it slowly, contrary to what he asserts. This is a very serious and very basic error for Sheldon considering he has a PhD in Physics.

Correction: This is wrong. Not only does he not mention energy anywhere, the commenter is not correct. This is not a mistake, just a different way of saying it (even though he didn't, rewatch the episode and find anything about work there).

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.

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 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

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

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

Most people yes, but Sheldon not being pedantic?

Moose

He could have corrected him later. We don't get to see everything they supposedly say to each other.

lionhead

Precisely. Plus it wasn't Sheldon that simply called it a "Nintendo DS." Leonard did. He's not as pedantic as Sheldon.

THGhost

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 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.

Stephen Hawking: Do you like brain teasers?
Sheldon Cooper: Oh, I love brain teasers.
Stephen Hawking: What do Sheldon Cooper and a black hole have in common? They both suck. Neener, neener.

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.
