Quote from Phoebe in The One with Rachel's Going Away Party
Chandler: Well, if they are not Monica's and they're not yours, then whose are they? Rachel: Well, I think you're forgetting the kinkiest former resident of that room. Chandler: Pheebs! Phoebe: Yeah! Chandler: I think these are yours. Phoebe: These are not mine. Look how flimsy they are. Come on. Good God. You try to hang a guy from a water pipe with these, they'll snap like a piece of licorice.
