Quote from Phoebe in The One Where Chandler Crosses the Line
Ross: You know, the sad thing is, if you had told him how you felt before you kissed her, knowing Joey, he probably just would have stepped aside. Chandler: Don't say that! That's not true, is it? Phoebe: Yeah, maybe. Monica: Yeah, he loves you. Chandler: Well, why didn't you tell me to do that? Ross: I said something to Phoebe. Phoebe: Yeah, that's right. And I thought it was a really good idea. Rachel: Yeah, I remember.
