Quote from Judy Geller in The One with Rachel's Book
Jack Geller: I remember when we first got engaged. Chandler: Oh, I don't think I've ever heard that story. Monica: Oh, Dad, you don't really- Jack Geller: Well, I'd gotten Judy pregnant. I still don't know how that happened. Judy Geller: You don't know how that happened? Your dog thought my diaphragm was a chew toy.
