As a major Friends fan, any mini reunion is a glorious one. Lisa Kudrow and Jennifer Aniston (a.k.a Phoebe & Rachel) reunited on Jimmy Kimmel Live! to play a hilarious round of Celebrity Curse Off! Here's how it works: the two are each given five seconds to come up with a curse word, no repeats allowed. By the time they run out of English words, Jennifer resorts to Greek and Lisa resorts to French. It's hilarious! Watch for yourself to see who the winner was:

How successful do you think you'd be in a round?
