The Agreement Dissection - S4-E21

Question: Since Sheldon had left the room, why didn't Leonard and Priya just hide the pen and lie and say that Leonard had signed the roommate agreement since Sheldon is so gullible?

THE GAMER NEXT DOOR

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

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.

The Justice League Recombination - S4-E11

Question: What is Raj's problem with Aquaman? Is it that he doesn't have powers?

THE GAMER NEXT DOOR

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.

The 21-Second Excitation - S4-E8

Question: I don't get why Amy invites herself to Penny and Bernadette's girls' night when she already made plans. Can someone please explain this?

THE GAMER NEXT DOOR

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.

The Engagement Reaction - S4-E23

Question: When they're at the hospital Howard never said that he told his mother that he was engaged, so how would Bernadette know he said that?

THE GAMER NEXT DOOR

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.

The Prestidigitation Approximation - S4-E18

Question: Why is Penny looking so happy when she sees Leonard and Priya in the restaurant and going into the restaurant and looking like she doesn't plan to leave and eats their food? Wouldn't Penny of all people know not to disturb someone during a date?

THE GAMER NEXT DOOR

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!

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 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.
