Quote from Kramer in The Non-Fat Yogurt
Elaine: Hurry, Jerry! Hurry! Jerry: How's it doing? Elaine: Not too good. Kramer: Well, you can't have this tested now. It's melting. Jerry: So what? Kramer: It changes the molecules. Jerry: Oh, you don't know what you're talking about. Kramer: Hey, fatso! I got a 90 in biology.
