Quote from Chandler in The One with the Birth
Monica: Has her water broken yet? Ross: I don't know, but when we talked, she said she'd already passed the mucous plug. Joey: Ugh, ugh. Do we have to know about that? Monica: Joey, what are you going to do when you have a baby? Joey: I'll be in the waiting room, handing out cigars. Chandler: Yeah, Joey's made arrangements to have his baby in a movie from the '50s.
