Monica: (Seeing a woman with newborn twins) No fair! I don't even have one! How come they get two?
Chandler: You'll get one.
Monica: Oh yeah? When?
Chandler: All right. I'll tell you what. When we're 40, if neither one of us are married, what do you say you and I get together and have one?
Monica: Why won't I be married when I'm 40?
Chandler: Oh, no, no. I just meant hypothetically.
Monica: Okay, hypothetically, why won't I be married when I'm 40?
Chandler: No, no, no.
Monica: What is it? Is there something fundamentally unmarriable about me?
Chandler: Uh, uh.
Monica: Well?
Chandler: Dear God! This parachute is a knapsack!
(Chandler throws himself over the back of the chair he was sitting in, pretending he can't open his parachute.)
