Quote from Phoebe in The One Where Chandler Takes a Bath
Phoebe: I know that things worked out for Chandler and Monica, but that's very rare. Joey: I know. I know. And this is so much more complicated than it was for those guys. I mean, it's Rachel, for God's sakes. Phoebe: For God's sakes, it's Rachel! Joey: I know. I know. And she's not only my friend, she's my pregnant friend. She's my pregnant friend who's Ross's ex. Phoebe: Yeah, that's Rachel. Beat me over the head with it.
