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?
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
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
Corrected entry: Sheldon makes fun of Leonard's idea to go to Raj's for dinner by speculating that they could stop using the letter M, which would be "isguided and oronic. Later he says that "This is adness. Complete and utter adness. He should have said "This is adness. Coplete and utter adness., leaving the M out of the word "complete" - and there is no way a pedantic, obsessive genius like Sheldon would make a mistake like that.
Corrected entry: Sheldon states that reductio ad absurdum is "the logical fallacy of extending an argument to a ridiculous extreme and then challenging it". This is incorrect; this is the straw man fallacy. Reductio ad absurdum is the entirely valid inferential technique of demonstrating that the consequences of an argument being true result in a contradiction.Moose
Corrected entry: When Penny and Sheldon get into the car to drive to the hospital, she makes the remark, "You do have a learner's permit, right?" He answers yes and explains he has logged several simulation hours which ended badly. She already knows he has a learner's permit and about the simulations, since in season 2, "The Euclid Alternative," she was with him at the DMV when he got the permit and stood beside him during the simulation, actually hitting him in the face with a pillow to mimic an airbag when he crashed.lizbeth1fl
Corrected entry: Kripke states that there is no guarantee that he will face Leonard, Sheldon, and Raj in the round-robin. In a round-robin, all competitors face each other in turn. It is out of character for Kripke not to be aware of this, and especially for Sheldon to not correct someone making this basic mistake.Jay32183
Corrected entry: Wil Wheaton tells Sheldon that he missed the convention because his grandmother died. When Wheaton later refers to a living grandmother, Sheldon realizes he has been tricked. He shouldn't - presumably Wheaton, like everyone else, has two grandmothers (mother's and father's side) and thus Wheaton announcing he has a living grandmother in no way contradicts what he said before. This alone shouldn't tip Sheldon off that Wheaton was lying.Moose
Corrected entry: Penny got a red light camera ticket while Sheldon was driving her car. She says she gave up Sheldon as the driver to the court because she didn't want to get any more points on her license. You don't get points on your license for a camera issued violation. The registered owner just gets a straight fine. A police officer has to issue a ticket at the scene to get license points.terry s
Corrected entry: At the end of the show Sheldon states on the walkie-talkie, "I spy with my little eye, a ferrous metal," Later he reveals that what he spied was the aluminum rims of a police car. Aluminum is a non-ferrous metal - definitely not a mistake Sheldon would make.allensis
Corrected entry: Kripke pumps helium into Sheldon's office to make his voice squeaky while conducting a phone interview. However, the helium is pumped in via a tube that is above the height of Sheldon's head, and helium floats in air; therefore, the helium would have accumulated near the ceiling and would not have affected Sheldon within a couple of minutes as shown.DavidK93
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
Corrected entry: When Leonard is explaining his thoughts to Sheldon, during the rant which includes him naming who he intends with the words she or her (eg "She: Penny, Her: Leslie), he states, "Indicating that She: Penny had no interest in me asking Her: Penny out," which makes no sense.
