As to be expected, Eminem goes berserk in his video for 'Berzerk.' No contemplation. No serious stares or looks -- save for his poker face during a card game scene. Instead, the rapper lets loose and has a whole lotta fun, accompanied by bearded producer Rick Rubin. There's also cameos from Kendrick Lamar and Kid Rock.

The video nods to the Beastie Boys' 'So What Cha Want' with its fuzzy and close camera angels. But it also includes footage of backyard wrestlers and a massive boombox.

It's old school Em in more ways than one. Watch and see.
