Every so often there one of the characters on The Big Bang Theory says something that is concise and insightful; something that no academic could possibly say about their own field quite so well: it has to be left to a comdey character instead. I have started collecting such quotes. In no particular order, here is the first:
Stephanie: ... So, how was your day?
Leonard: Oh, you know, I’m a physicist, so, I thought about stuff.
Stephanie: That’s it?
Leonard: Well, I wrote some of it down.
