Freestyle rap

Host Jimmy Fallon was floored by the hip-hop star's improv in a game of "Wheel of Freestyle."

Rapper Mistah F.A.B. grew up in Oakland in the 1980s during the crack epidemic, with both of his parents battling drug addiction. He had to grow up quickly, and used rap as a way to cope and express himself.

Colin Kaepernick, Sean Diddy Combs, Ellen DeGeneres and a whole host of other famous faces also chimed in.
