Ross: (about the set he just played) Yeah, I lost it... (to Phoebe) Y'know what? I'm not gonna play anymore. Would you... Can you finish my set?
Phoebe: After that? Yeah! (less insensitively) No, I mean, if I can help...
Ross: (after Phoebe leaves, to Monica and Rachel) Yeah, like I could "lose" it.
Ross: I played bad on purpose, guys...
(Monica and Rachel both laugh)
Monica: Okay, so you were trying to play bad this whole time?
Ross: Yeah... no! Just that last song.
