Quote from Ross in The One Where Chandler Can't Cry
Monica: What's going on? Joey: Phoebe's a porn star! Chandler: What? Joey: Yeah. Rachel: What are you talking about? Chandler: "Phoebe Buffay in Buffay The Vampire Layer." Rachel: Oh, my God. Monica: That's Phoebe. Where did you get that? Joey: Down at the adult video place on Bleecker. Ross: And I saw Joey was about to go in, so I ran in ahead of him to surprise him. And then I pretended that I didn't know he was in there.
