Quote from Joey
Joey: Hey, Rach? Sorry to interrupt, but Phoebe said you want to talk to me about a trip or something?
Quote from Joey
Phoebe: Kip didn't even have to be Kip. We handled that all wrong. It was a long time ago.
Joey: Yeah, Rach. And it was before you and me were around. They didn't know what they were doing. Chandler had a mustache for crying out loud.
Quote from Chandler
Joey: So your weekend was a total bust?
Chandler: No, I got to see Donald Trump waiting for an elevator.
Joey: You know, at the Taj Mahal, he has his own private glass elevator. That's right. Made by Otis Elevators. And they usually don't do glass.
Chandler: What kind of stuff do you know?
