Quote from Chandler in The One with the Boobies
Roger: You're so funny! He's really funny. I wouldn't wanna be there when the laughter stops. Chandler: Whoa, whoa. Back up there, sparky. What did you mean by that? Roger: Well, I don't know. It just seems that maybe you have intimacy issues. You know, that you use your humor as a way of keeping people at a distance. Chandler: Huh. Roger: I mean, hey, I just met you. I don't know you from Adam. Only child, right? Parents divorced before you hit puberty. Chandler: Uh-huh. How did you know that? Roger: It's textbook.
