Watch Kevin Hart and Jimmy Fallon Slap Each Other With Giant Hands

Kevin Hart on Fallon - H 2015

The duo play 'slapjack' on 'The Tonight Show.'

Jimmy Fallon busted out another one of his games last night during a visit from Kevin Hart. Hart was promoting The Wedding Ringer and talked about his Hollywood Reporter cover shoot, but he also had some fun with Fallon and giant hands.

Fallon and Hart played "slapjack," which is like blackjack, but includes enormous hands used to slap your opponents with when they lose. Watch as the actor and late-night host make noises and joke awkwardly about mothers-in-law and the number 17.
