Video: Jimmy Kimmel Is F*&)cking Ben Affleck

The long-running "feud" between Matt Damon and late-night TV host Jimmy Kimmel reached new heights earlier this month when Damon shot a video in which Kimmel's comedian girlfriend, Sarah Silverman, declared she was "fucking Matt Damon." Immediately after the Oscars last night, Kimmel fired back with a truly epic effort called "I'm fucking Ben Affleck," which included appearances from celebrities like Harrison Ford, Cameron Diaz, Don Cheadle, Robin Williams and Huey Lewis, to name just a few. The Kimmel-Damon fight is, of course, wholly manufactured, but at least has been consistently funny, starting with Kimmel's regular end-of-show gag, "Apologies to Matt Damon, we've run out of time," and extending through to Damon's on-air tantrum about getting bumped and two gags involving Kimmel's special correspondent, Guillermo. Kimmel's latest Ben Affleck video takes the joke to new lengths -- and new heights in the art of free PR:

Celebrities included in the video, according to Kimmel's people: Harrison Ford, Cameron Diaz, Don Cheadle, Robin Williams, Huey Lewis, Rebecca Romijn, Macy Gray, Pete Wentz, Dominic Monaghan, Joel and Benji Madden, Josh Groban, Christina Applegate, Meat Loaf, Perry Farrell, Lance Bass, Joan Jett and Christopher Mintz-Plasse. Plus a gospel choir and whoever the delivery man was -- an unnamed "superstar."
