Watch Chris Pine Slap Jimmy Fallon in the Face With a Giant Hand (Video)

Chris Pine and Jimmy Fallon slapped each other around on Thursday night’s episode of “The Tonight Show.”

Fallon invited the “Star Trek” star onto his program for a game of “Slapjack,” which he described as a riff on blackjack, where whoever wins the hand gets to slap the other player with a giant prosthetic hand.

Before the game got underway, Pine had some fun with his giant left appendange, grazing Fallon’s crotch.

“It’s the second time I’m playing blackjack,” the actor admitted.

The pair then launched into the card game, barely able to contain their laughter. Fallon won the first round.

“Dude, you’re going to be so great at ‘Saturday Night Live,’” he told his guest. (Pine is hosting this week’s episode.) “I’m so excited I can’t wait to watch.”

Then Fallon slapped Pine — gently.

Fallon won the second, but Pine broke to rules and tapped the host on top of his head, unable to help himself.

Lucky for Pine, he won the third and final round. He relished his victory with a direct slap to Fallon’s face. It looked a bit painful.

Pine’s episode of “Saturday Night Live” marks the second of four historic episodes in which NBC broadcasts the sketch comedy series live across all times zones in the United States. LCD Soundsystem will be this weekend’s musical guest.
