Mark Walhberg smacks Jimmy Fallon in the face on The Tonight Show (VIDEO)

Mark Wahlberg played 'Slapjack' on The Tonight Show starring Jimmy Fallon last night.

Mark and Jimmy played hands of blackjack and the loser of each round (hand) got slapped in the face with a prosthetic hand. Hahaha.

Wahlberg suggested that he should have brought his prosthetic penis from Boogie Nights instead.

This. Is. So. Funny.

It's like something from Japanese TV, love it!

Watch the video here:

Jimmy and Mark Wahlberg compete in a high-stakes game of blackjack where the loser of each round gets smacked in the face with a giant rubber hand.
