Diane: I think by now your curiosity is satisfied, your inexplicable lusts sated. If our relationship remains as strong and vital as it is now you'll have no need for sexual experience with another woman.
Sam: Oh, my God.
Diane: What do you mean, "Oh, my God?"
Sam: I- I just never thought about that before. My last woman.
Diane: You do agree, don't you?
Sam: Uh, I don't know.
Diane: Why not?
Sam: Hey, come on. Something could happen to you. You know, you could die or go insane or... What happens if you don't age well? What would happen if I went down in an airplane over South America some place and was taken captive by a tribe of huge women who made me their sex slave. Forced by High Priestess Bettina and her handmaidens to satisfy them day after day after day. Come on. Be realistic, Diane.
