We noted last week that Jimmy Kimmel would be premiering a response video to girlfriend Sarah Silverman's "I'm F*cking Matt Damon" video last night in his post-Oscar show, and did he ever. Not only is Jimmy f*cking Matt's BFF Ben Affleck, but he's got Cameron Diaz, Brad Pitt, Robin WIlliams, Don Cheadle, Harrison Ford, Lance Bass, Macy Gray, Joan Jett, Huey Lewis, Rebecca Romijn, and slews more friends there to help share the news.

The whole "like they're in prison" joke and the ridiculous outfits that "gay" Jimmy and Ben wear are pretty groan-worthy, but the Josh Groban appearance really makes it all worth watching.

Thoughts?
