Monica was undoubtedly the most competitive character on "Friends", and it seems like that trait may have rubbed off on — or been inspired by — the actress who played her.

During her appearance on "Ellen" Tuesday, Courteney Cox was challenged to a "Friends"-themed round of the trivia game "Heads Up!" and the former Central Perk regular put on a performance that would make even Monica proud.

"You better do well at this!" Ellen DeGeneres said as she introduced the game.

Cox handled the quiz with relative ease, but not without a few bumps in the road. Watch the video to see which questions she struggled with, and to see her hilarious impression of Ross's famous "We were on a break!" line.
