Jennifer Aniston And Lisa Kudrow Curse At Each Other On 'Jimmy Kimmel Live!'

Two of the "Friends" cast reunited Monday night for some very unfriendly behavior. Jennifer Aniston and Lisa Kudrow faced each other in a "Jimmy Kimmel Live!" segment called "Celebrity Curse Off." In the game, each participant gets five seconds to craft an original phrase directed at their opponent. As would be expected from the funny "Friends" ladies, the creations get pretty out there.

If the video proves anything, it's that even in the midst of throwing jabs, these two have totally infectious chemistry.
