Because games involving physical and psychological torment are pretty high on Jimmy Fallon‘s list of interests, he invited recent guest Gerard Butler to play a game of slapjack.

Slapjack is very much like regular blackjack, except at the end of each round, the winner gets to slap the loser with a giant, prosthetic hand. (Ryan Reynolds also gave this very grown-up game a crack last year).

It turns out watching adult men slap each-other silly with giant appendages is never not funny. Speaking of giant appendages, Gerard Butler also has one he’s keen to introduce you to. Enjoy:
