Quote from Kelso in Mother's Little Helper
Kelso: All right, Fez. Come on, I need your help. Fez: Why should I help you? Kelso: Because you owe me. Think about all the times that I set you up with my dates' less-pretty friends. Fez: That's true. You have thrown me some uggos. Kelso: All right, so show a little appreciation.
