Sarah Silverman + Matt Damon Prank Jimmy Kimmel – Celebrity Pranks
In one of the best-known celeb pranks, back in 2008 comedienne Sarah Silverman went on her then-boyfriend's show 'Jimmy Kimmel Live!' to tell him a secret. A surprise, if you will, of epic proportions.
On the program, Silverman instructs the crew to roll the clip she brought, in which she sings a song about how she's cheating on Jimmy with his nemesis Matt Damon.
The song is unsurprisingly called 'I'm F---ing Matt Damon' -- and features the man himself singing along.
