One of my favorites from the sixth season, along with "Ross Got High" and "Joey Loses His Insurance". This is the best dialogue from it:

Phoebe: (entering) Hey!

Monica: Hey!

Phoebe: Okay, I just thought of the perfect guy for Rachel to take to her thing.

Chandler: Oh that’s so funny because we found someone too.

Phoebe: Oh that’s good, I guess she’ll have a choice between my guy and your weirdo.

Chandler: Why would our guy be a weirdo?

Phoebe: ‘Cause that’s just your taste.

Monica: (laughs sarcastically) Rachel is not going to pick your stupid guy.

Phoebe: Oh yeah?

Monica: Yeah!

Phoebe: My guy is a lawyer who has volunteer work. And, he has one of these (She squeezes the skin on her chin together to form…)

Chandler: A face ass?

Phoebe: A chin dimple!

Monica: Well, uh y’know, our guy works with Chandler and he’s really nice and smart and he’s a great dresser!

Phoebe: Have you seen your guy’s body?

Chandler: No, our guy is just a floating head.

Phoebe: Well my guy is spectacular. Okay? He’s a massage client and one time umm, when he was on the table, I looked at it. And I mean all of it.

Monica: You’re not supposed to look!

Phoebe: Oh yeah, like there are police for that!

Chandler: (horrified) Wait! You look? You-you massaged me.

Phoebe: I know. (Laughs.)

Monica: All right fine, your guy may have a great body, but our guy is really funny.

Phoebe: Oh, Chandler funny?

Monica: Our guy’s a great dancer!

Phoebe: My guy is well read.

Chandler: Our guy has great hair.

Phoebe: My guy has great teeth!

Chandler: Our guy smells incredible.

Monica: (To Chandler) Do you want our guy to be your guy?

Ha! I love it! (And I hope you do too.)
