"Where does rage like that come from, Jimmy?"

Ryan Reynolds played "Slapjack" with Jimmy Fallon to promote his new gambling movie, Mississippi Grind.

The premise of the game is that it's like blackjack — except when a player loses, he or she gets slapped in the face with a giant hand. When Reynolds lost the first round and Fallon slapped him, Reynolds asked the host, "Where does rage like that come from, Jimmy?"

The actor kept joking around with Fallon, saying, "Weirdly, it was your eyes that flashed before my eyes."

The duo went on to slap each other around a little more, hamming it up for the cameras and talking about NFL concussion protocol. Watch below.
