Happy anniversary, Jimmy Kimmel, you’ve been cuckolded by People magazine’s Sexiest Man Alive! The late-night host’s longtime girlfriend, comedian Sarah Silverman, teams up with the Bourne star (and long-running Kimmel Show punch line) to give her honey a present he won’t soon forget—with bonus points for butterflies, mid-song breakdown, and the Good Will Hunting reference. To say any more would spoil it, so just watch. (Warning: despite bleeps, it may be NSFW.)
Oh, and it turns out, it’s not the first time Damon has jacked a man’s ladyfriend onscreen. Remember this little gem from Eurotrip (embedded after the jump)?
