Maynard James Keenan isn't just the super creative and brilliant mind from the band Tool, he's also a Brazilian jiu jitsu brown belt. Clearly Chris Rock should have been training with MJK to better prepare to defend himself against that slap to the face from Will Smith.
MJK is with some of his training friends at a gym in Arizona when he demonstrates with ease a move he calls the "cuck block," an elbow throwing maneuver that would have shielded Chris Rock's face from being slapped.
