Even Friends can exchange harsh words! Jennifer Aniston and longtime pal and former costar Lisa Kudrow got extra feisty on Monday, Nov. 24, while competing in Jimmy Kimmel Live’s “Celebrity Curse Off” game. 

The Friends stars were each given five seconds to come up with a brand-new curse word, and whoever failed to do so lost the game. The beloved contest was recently played by Steel Magnolias costars Julia Roberts and Sally Field

Aniston, 45, started off the night with “d—k licker,” to which Kudrow, 51, replied “c—sucker.” Proving they really are friends, the pair burst out laughing at each other’s responses and apologized to one another for particularly nasty phrases.
