Jimmy Kimmel is doing what with Ben Affleck?

A couple of weeks ago, Sarah Silverman showed off the video she made with Matt Damon. It was a little parody where she jokingly went on about having sex with Matt Damon. Well, it's time for Jimmy Kimmel to fire back . . . and it looks like his budget was a little bigger than Silverman's. He's got Ben Affleck, Brad Pitt, Don Cheadle, Robin Williams, Dominic Monaghan, Harrison Ford, Christina Applegate, Cameron Diaz and that kid that played McLovin in "Superbad". I know there are a ton more people in this that are famous, but I didn't know their names. Enjoy the video.
