Foo Fighters turn in another memorable video with 'Learn to Fly,' which features a cameo from Jack Black as an airline worker who stashes his weed in a commercial jet's coffee pot. Hilarity ensues when everybody on the plane -- passengers, flight attendants and, of course pilots -- drink some Joe and get super stoned. Luckily, Dave Grohl and the rest of the Foos skip the java in favor of the hard stuff and are able to come to the rescue.

Music videos are nothing new for Jack Black, who, in addition to appearing in his own Tenacious D clips, has made cameos in Beck's 'Sexx Laws,' Weezer's 'Photograph,' the Eagles of Death Metal's 'I Want You So Hard (Boy's Bad News)' and even two other Foo clips, 'Low' and 'The One.'
