Quote from Ross in The One with Phoebe's Wedding
Phoebe: But I don't wanna choose. It's- Ooh. Okay, wait. Rach? Rachel: Yeah? Phoebe: Listen, I have a very special bridesmaid task for you to do. Rachel: Goody! What is it? Phoebe: Well, there's a spot open for only one groomsman and you have to choose between Ross and Chandler. So good luck with that. Rachel: What? What, what, what? No, I don't wanna do that. Phoebe: All right, I guess I have to find a new bridesmaid. Ross: I'll do it!
