Ross: What, so this guy is helping you for no apparent reason?

Rachel: Uh-huh!

Ross: And he's, he's a total stranger?

Rachel: Yeah! His name is um, Mark something.

Ross: Huh. Sounds like Mark Something wants to have some sex.

Rachel: What!?

Ross: Well, I'm just saying, I mean why else would he just, y'know, swoop
in out of nowhere for no reason.

Rachel: To be nice.

Ross: Hey, Joey. Are men ever nice to strange women for no reason?

Joey: No, only for sex.

Ross: Thank you.
