Quote from Jack Geller in The One with the Prom Video
Judy Geller: We were so sorry to hear about your parents splitting up.
Rachel: Oh. Well, they're just separated. So you never know. We'll see.
Jack Geller: Well, I can't say any of us were surprised. Your parents have been unhappy ever since we've known them. Especially after that incident in Hawaii.
Rachel: What? What incident?
Jack Geller: Um, no, no. I must be thinking of someone else. Maybe me. Don't you have some folding to do? Go fold, dear. Fold. You fold.
