If you thought Sarah Silverman's "I'm F**king Matt Damon" was the most hilarious video you'd ever seen, wait till you get a load of what Jimmy Kimmel did to strike back last night during his post-Oscar show. Not only did he whip up a ridiculously brilliant video featuring Matt Damon's "other half," Ben Affleck, as his love interest, but he also went on to recruit what appears to be all of Hollywood to serve as backup singers. Robin Williams, Don Cheadle, Cameron Diaz, Lance Bass, Josh Groban, Harrison Ford - it's an endless list! Brad Pitt even makes a cameo as the Fed Ex guy. All we can say after watching them walk away together in their cut-off short-shorts? Awesome. Just plain awesome.

**Note: If the video is loading slowly, sit tight - a lot of people are trying to watch this at the same time!

Your take: Whose video do you think was better, Sarah's or Jimmy's? We love Sarah's and the fact that she came up with this whole thing to start with, but we have to admit, Jimmy outdid himself on this one! Thoughts?
