Gerard Butler [1] has been keeping a low profile as of late, which made his Thursday night appearance on The Tonight Show Starring Jimmy Fallon that much more special. The London Has Fallen actor [2] was hilarious as always as him and Jimmy played a game of Slapjack, which is like Blackjack, only the loser of each round gets slapped in the face with a giant rubber hand. Unfortunately luck wasn't on Gerard's side, and Jimmy got to take a few shots at the Scottish action star [3], saying, "I can't believe I just hit Gerard Butler in the face!" Watch the funny video above, and check out the trailer for Gerard's new movie Gods of Egypt [4].
