Big Bang Theory Quote
Penny: You are a grown man. Haven't you ever been sick before?
Sheldon: Of course. But not by myself.
Penny: Really? Never?
Sheldon: Well, once, when I was fifteen and spending the summer at the Heidelberg Institute in Germany.
Penny: Studying abroad?
Sheldon: No, visiting professor. Anyway, the local cuisine was a little more sausage-based than I'm used to, and the result was an internal blitzkrieg, with my lower intestine playing the part of Czechoslovakia.
