Hit me! Much to his own detriment, Jimmy Fallon unveiled a new game on The Tonight Show on Wednesday, Dec. 10. The host and his guest Mark Wahlberg tried their hand (see what we did there?) at “Slapjack” — a new version of blackjack in which the loser gets hit in the face by a giant prosthetic hand, courtesy of the winner.  

“You should have told me! I would have brought my giant prosthetic penis from Boogie Nights,” Wahlberg, 43, joked. 

The Gambler star started off the game, taking jabs at Fallon and others throughout. When the host questioned Wahlberg’s lead, he teased, “I’m not Ben Affleck, I’m not counting cards!”

Affleck admitted to getting kicked out of a Las Vegas casino for counting cards in the October issue of Details. It’s a skill that Wahlberg’s Gambler character Jim Bennett possesses in the upcoming film. 

The two-time Oscar nominee told Fallon that his eldest daughter, Ella Rae, 11, wants to break into the business. 

“My oldest daughter really has the bug,” he said. “She did a little part in Transformers, but I told her no movies until she graduates. I’m trying to discourage them from going into this business because, you know, it’s a tough racket. But they’re going to do what they want to do.”
