Quote from Joey in The One with Phoebe's Husband
Chandler: Joey was in a porno movie. If I'm going down, I'm taking everybody with me! Rachel: Oh, my God! Ross: You were in a porno?! Joey: All right, all right. I was young and I just wanted a job, okay? But at the last minute I couldn't go through with it. So they let me be the guy who fixes the copier but can't because there's people having sex on it.
