Gerard Butler And Jimmy Fallon Played Slapjack With Giant Hands

This game looks like way too much fun.

In a delightful segment for The Tonight Show, Scottish actor Gerard Butler joined host Jimmy Fallon for a mischievous little game of "Slapjack." 

"It works the same as blackjack, but at the end of each round, the winner gets to slap the loser across the face with a giant prosthetic hand," Fallon explains.

The pair take turns dealing and the first to win three rounds is crowned the champion. But don't worry, they both feel like winners in the end. 

Because, by the looks of it, slapping someone in the face with a giant prosthetic hand is exactly as fun as it sounds.

Watch Butler make some sexual innuendos and whack Jimmy Fallon in the video above.
