Rachel Green and Phoebe Buffay definitely got into their fair share of trouble on "Friends," but they certainly never used the type of potty-mouth language that Jennifer Aniston and Lisa Kudrow threw out on "Jimmy Kimmel Live" last night (November 24).
The actresses -- who are starring in "Horrible Bosses 2" and "The Comeback" respectively -- bravely competed in Kimmel's famous "Celebrity Curse Off," where they each had five seconds per round to come up with cusses like "dick licker," "holy f--- balls," and "s--t for brains."
Adorably, Aniston almost lost it when Kudrow threw out "f---ing s--t," -- because "she used to say it all the time" on the "Friends" set -- but she quickly pulled it back together with a dirty Greek no-no word. (Another highlight was Kudrow throwing out the classic "ch--d," then blaming her son for her knowledge of the word.)
