Question: I know the Big Bang Theory has hired scientists and physicists to write the technical science parts of the scripts and the white board equations. Since Mayim Bialik has a doctorate in neuroscience, does she collaborate with the writers to write those parts of the script?
Answer: She has helped them out when she can, but this is not part of her formal contract with the show.
Question: In this episode, Amy deduced that if Indy wasn't in Raiders of the Lost Ark it still would have ended the same way. If I remember correctly, Major Toht was on the plane with him. Doesn't this look like the Nazis didn't know where to find Marion, and were following Indy?
Answer: The agent on the plane watching Indy was not Toht, and was played by ILM staffer Dennis Muren, although they look similar. The Nazis were spying on Indy but this doesn't mean they didn't know where the Ravenwoods' bar was.
Question: Is it out of character for Sheldon to willing go donate sperm just for money considering that he has no interest in sex?
Answer: Sheldon believes himself to be superior to all other humans and therefore his lack of desire for sex is only superseded by his desire to create a superior sub-species of human. This concept is also seen later in the series when he and Amy consider having a baby together to make a super smart child (by invitro of course).
Question: Why does the show go out of the way never to show the names of sodas? IE, 'Cola' instead of 'Coke', 'Lime' instead of 'Sprite,' 'Zip' instead of '7up.' They don't seem to have a problem with showing names of other products, such as the snacks in the vending machine.
Answer: Certain items are part of paid product placement. Those would be obviously named, as would things that can't go unnamed for simplicity reasons. Other things might be unnamed because of opposite product placement, i.e. Coke pays for it so they don't name Pepsi products.
Question: I don't get it. Sheldon and Kripke are bad at sports. At the end, they are both sweating and breathing hard. But in 6-13 The Tenure Turbulence, Leonard can't last on the treadmill but this time Kripke can run on the treadmill for a long time yet one season ago, he can't run without breathing so hard. What's going on?
Answer: The simple answer would be "he must have trained and gotten fitter." If it were the other way around, fit then a season later unfit, it would be more confusing.
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?
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!
Question: In the majority of the episodes, whenever one of Howard's friends, or he himself, knocks on his front door his mother yells out, "Is that a sex criminal" or something along those lines. Is that referencing anything in particular?
Answer: I can only recall one episode where this happens more than once. Perhaps there are others episodes where this line is spoken but this does not occur enough times to be a specific reference or a regular on-going theme.
