The Big Bang Theory

Chosen answer: Sheldon would certainly check the contract for a signature afterwards. Sheldon also notarizes every contract he writes or signs.

Greg Dwyer

Answer: In a situation where he wants to get his own way, he turns to the roommate agreement and for this situation would see an empty space.

The Herb Garden Germination - S4-E20

Question: In the beginning, Sheldon and Amy are attending a reading (or lecture) of Brian Greene. It seems Sheldon is truly mocking, although at the end he says he's kidding. Do theoretical physicists consider Greene to be a hack, or is he respected in the field of physics? Are Sheldon and Amy truly laughing at him?

Bishop73

Chosen answer: He's respected. Sheldon just thinks he knows more than anyone else and mocks anyone whose theories don't agree with his completely. Amy is probably just going along because it makes Sheldon happy.

Captain Defenestrator

Answer: Aquaman does in fact have powers. It is a long running joke that Aquaman is not a useful member of the Justice League due to a seemingly useless set of powers.

Chosen answer: She figured it out from what he did say. Since their engagement is a relatively recent development, it's an easy deduction that the shock of such a huge step in their relationship is what knocked his mother for a loop.

Cubs Fan ★

Chosen answer: She's having a Leonard moment and not fully grasping the situation. She doesn't see her ex boyfriend and his new girlfriend having a romantic dinner, but two of her friends having a meal. Whether it was conscious or unconsciously is anyone's guess.

The Desperation Emanation - S4-E5

Question: In this episode, when Amy is waiting outside for Sheldon because she was told he wasn't home when she arrived to see him, Sheldon is coming down the stairs. As he does so, he is singing a peculiar song and skipping steps. Why is he doing this? Is there something I'm missing?

OliviaD3601

Chosen answer: Sheldon has been shown to a) be a little weird and b) like to pass his commuting time exercising his mind with brain teasers and such. The song in the episode "The Desperation Emanation" names the star systems closest to our solar system, in order, from closest to furthest away. Typically of Sheldon, if he gets it wrong, he has to start again, or it isn't right!

SexyIrishLeprechaun

Answer: There's several factors that mainly revolve around Amy never having any real girl friends growing up (she had never even been to a slumber party). Also, she never had a girls night out before and would rather do that then hang out with boys. She was only going to the movie because Sheldon was going, but had no real interest in it. She also wants to spend as much time with Penny as possible.

Mistakes

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.
