CHANDLER: OK, what is it about me? Do I not look fun enough? Is there something repellant about me?
ROSS: So, how was the party.
CHANDLER: Well it couldn't have been worse, a woman literally passed through me. OK, so what is it, am I hideously unattractive.
PHOEBE: No, you are not, you are very attractive. You know what, I go through the exact same thing. Every time I put on a little weight, I start questioning everything.
CHANDLER: Woah, woah, I've put on a little weight?
PHOEBE: No, not weight, ya know, more like insulation.
MONICA: Chandler, I'm unemployed and in dire need of a project. Do you wanna work out? I can remake you.
CHANDLER: Oh, you know, I would but that might get in the way of my lying around time.
ALL: C'mon. Let her. Yeah.
CHANDLER: Alright, OK, alright. But if we put on spandex and my boobs are bigger than yours, I'm goin, home.
PHOEBE: Your boobs are fine. Look, I never should have said anything. Come here. Come here. Oh, can't make hands meet.
