Jimmy Kimmel Is F*%ing Ben Affleck. His Star-Studded Video Response To Matt and Sarah

Jimmy Kimmel's star-studded video response to Sarah Silverman's "I'm F*^ing Matt Damon.
Some of the stars that appear in this video are Brad Pitt, Robin Williams, Cameron Diaz, Don Cheadle, Harrison Ford, Joan Jett and others. The video is funny but I think Sarah's and Matt's video is funnier!
