The home video footage is shocking enough: Inside a divey hotel room, Foo Fighters frontman Dave Grohl wiggles his tush and wriggles out of a pair of tight white shorts, then dances around in a women's tank top, stockings and a garter belt before flinging a shoe at the camera.

What's perhaps even stranger is that the clip is a scene from the Foo Fighters' video for "Low," the next single from the band's most recent album, One by One.

The entire video will feature Grohl and actor/Tenacious D frontman Jack Black dressed in drag and goofing around, said the band's publicist. In one scene, Black is filmed wearing a curly black wig, baseball cap, pink bikini top and pair of shorts decorated with hearts while Grohl, in a blonde wig, applies lipstick in a mirror. The scene is capped by Black grabbing his crotch.

Later, Grohl writhes on the bed in a pair of black panties. In the most bizarre scene, Grohl perches on all fours and Black spanks him from behind. Then the camera cuts to a long shot of their four legs twitching and intertwined.

The "Low" video features the most intimate tape of Grohl and Black together, but their relationship is far from a fling. Black first appeared with Grohl in the 1999 Foos video for "Learning to Fly," then Grohl played drums on the 2001 Tenacious D record and guest starred in the band's video for "Tribute."
