Jennifer Aniston and Lisa Kudrow Get Filthy on 'Kimmel'

Former 'Friends' become fierce competitors on the late-night show's 'Celebrity Curse-Off' challenge

Jennifer Aniston and Lisa Kudrow went head to head in a battle of words on Jimmy Kimmel Live! Monday night — not Scrabble, Boggle or even Words with Friends (get it?), but rather Kimmel's classic game-show bit "Celebrity Curse-Off."

Kudrow and Aniston proved to be formidable opponents, unleashing some truly foul language in the five seconds allotted for each term. The pair unleashed a torrent of four-letter words (and their  hyphenated variations), with Aniston busting out a Greek swear and Kudrow going French. Despite the heated exchange, Kudrow eventually found herself at a loss, shouting the completely non-offensive "Snap pants!" and effectively handing Aniston the win.

This is not the first time the former Friends castmates have appeared together on Kimmel: Over the summer, the host corralled not just Rachel Green and Phoebe Buffay, but Monica Geller herself, Courtney Cox, to act out a scene from his outrageous Friends fan fiction. As for the guys? Kimmel explained they'd died after being bitten by Marcel the monkey and contracting monkey rabies.

At the time, the trio was celebrating the 20th anniversary of Friends, though now Aniston was on-hand to talk about the upcoming Horrible Bosses 2, while Kudrow has been on the promotional trail for The Comeback, her beloved cult comedy that recently returned to HBO for a second season after nine years.
