Watch Beastie Boys' rare 'Chappelle's Show' performance, which features the legendary group rapping on a boat.

The title of the video has 'Middle Finger to Viacom' in it, which is a dig at the company for pulling the video when Neal Brennan, the co-creator of Comedy Central's Chappelle's Show, uploaded it on the weekend. The rare clip had previously never been seen, so watch it before it disappears again.
