Diane: No, I won't be coming back, but I will. [laughs] I guess I just made up a little Zen koan, didn't l?
Frasier: Let me explain. A koan is a paradox upon which one meditates in order to become more enlightened. Uh, well, for example, what was your face before your parents were born?
Sam: Easy. A ten. This is kind of fun. You got any more?
