Childish Gambino is the latest rapper to take part in Sway In The Morning's "5 Fingers of Death" freestyle challenge. With a canvas of five rotating beats behind him, the rapper-actor spits a flurry of metaphors, punch lines, and, in his words, "nonsense." It gets a little messy when DJ Wonder throws on Nirvana's "Come As You Are," but, as Gambino says himself, those mistakes are the whole point of what he's doing. You can watch the freestyle session above.
