Quote from Chandler in The One with Joey's Dirty Day
Chandler: Phase three! I just achieved phase three. I am totally picturing you with all those women. Monica: That's not phase three. Chandler: Well, I'm there too. Rachel: Well, are we all together, like in a group? Chandler: Stop it, you're killing me. I think I just moved onto phase four. Phoebe: What is that? Chandler: Where I don't want a relationship ever. I just want to have sex with strippers and my friends.
