Question: Though it comes up in other episodes as well, this one is focused on Sheldon needing a ride everywhere he goes because he can't drive, not to mention his not being welcome on the bus. Of course, this story element would be nonexistent if there was a simple answer, but it does beg the question: Does Pasadena not have taxicabs?
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.
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?
Question: My understanding is Sheldon, Leonard, Raj, Howard, and even Amy and Kripke work for a university; but none of them seem to be teachers. And if they are, they never have office hours, or are seen grading homework, and Sheldon seems inept at teaching. Do universities really hire that many people who simply do research with no actual work requirements? Or what's going on? (I understand not filming boring office hours or grading, etc. But they never even allude to it, their work never interferes with random daily events, and I imagine college teachers/professors would stay extremely more busy.
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?
