Quote from Chandler in The One with Two Parts: Part 2
Chandler: So, what are you gonna do? Joey: What can I do? Look, I don't want to do anything to screw it up with Ursula. Chandler: And your friend Phoebe? Joey: Well, if she's my friend, hopefully she'll understand. I mean, wouldn't you guys? Chandler: Man, if you tried that on my birthday you'd be staring at the business end of a hissy fit.
