Sarah Silverman performs on stage at Comedy Central's "Night of Too Many Stars" special on Sunday, April 13, 2008, in New York. Silverman started an instant YouTube sensation when she appeared as a guest on "Jimmy Kimmel Live!" to show Kimmel, her boyfriend, a special video. The video turned out to be a song called "I'm F***ing Matt Damon," in which she and Damon sang a duet about having an affair behind Kimmel's back.
