The Adhesive Duck Deficiency - S3-E8
Corrected entry: There is no way Sheldon would have been able to hear Penny call him for help as as he did, through four closed doors, two rooms and a hallway.
The Clean Room Infiltration - S8-E11
Corrected entry: Howard and Leonard contaminate the "clean" (sterile) room by allowing a bird into the room. The very first thing they should have done is cover all of the sterile instruments strewn over the worktable. But they did not.
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.
The Friendship Algorithm - S2-E13
Corrected entry: When Sheldon was stuck in an infinite loop in his "friendship flowchart", Howard created an escape which he labeled "LDA"; however, Sheldon referred to it as "Least Objectionable Activity", which would be "LOA."
Correction: It is easy for a D to look like an O.
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.
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.
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.
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 produces a foam mass that is dangerously hot, 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.
The Cognition Regeneration - S10-E22
Corrected entry: Raj claims he never learned Hindi, but he's spoken Hindi many times in previous seasons.
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.
Correction: Barry doesn't always mispronounce the letter R. It can happen with certain Rs and Ls.
The Werewolf Transformation - S5-E18
Corrected entry: In the start, the other barber replacing Sheldon's old barber refers to Mr. D'Onofrio as "Uncle Tony," but when Sheldon goes to visit Mr. D'Onofrio and the nurse walks in, the hospital board says A. D'Onofrio, which isn't the right initials. (00:08:10)
Correction: A for Anthony, which is often shortened to Tony.
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.
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.
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.
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.
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)
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).
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)
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.
The Wheaton Recurrence - S3-E19
Corrected entry: In previous episodes, it's mentioned that Leonard is lactose intolerant, but at the bowling alley he eats from a plate of chili cheese fries.
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.
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.
The Raiders Minimization - S7-E4
Corrected entry: When Leonard and Penny are doing the 'business' at the university and Howard knocks on the door, Leonard opens and says "hey Si" (Howard's real name - Simon Helberg).
Correction: He says "Hey, sorry," while panting - he's apologising for taking so long to answer the door.
The Monster Isolation - S6-E17
Corrected entry: When Leonard tells Sheldon to hand over his Nintendo DS, Sheldon gives him a shiny aqua console. The Nintendo DS has never been produced in that color: the console is actually a 3DS, not a DS.
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.
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.
