After previously forcing the three female Friends to act out his fan fiction screenplay a couple months ago, Jimmy Kimmel had Jennifer Aniston and Lisa Kudrow back to Jimmy Kimmel Live for something with a decidedly different tone: “Celebrity Curse-Off.”

The concept of the game is simple. Basically, you have five seconds to come up with a curse word. No repeats. And you go back and forth until somebody can’t come up with one.

Aniston gets points for using a foreign language, but Kudrow seems to have the edge in cursing enthusiasm. Her whole body basically shakes when she swears at Aniston. As for the winner? You’ll have to check out the clip.
