Jake Gyllenhaal and Jimmy Fallon slap eachother in a hilarious game they called a "Slap Jack," which is basically a game of Black Jack only with the addition of a giant rubber hand.
"It's the same as Black Jack and the winner gets to slap the loser across the face with a giant prosthetic hand," Fallon explains, pulling out a giant rubber hand that he wore on his right hand. "The first to win three rounds is the winner -"
As the TV show host explains the rules of the game they invented, Gyllenhaal interrupts him.
"Wait, that's not cool man," the actor said.
"What do you mean?" Fallon said.
"Why don't I get one?" Gyllenhaal said, referring to the giant rubber prosthetic Fallon wore on his uninjured hand.
Fallon laughs and explains: "Your hand is big enough!"
"You're right, I'm kidding," Gyllenhaal laughed, then, jokingly (and awkwardly) said, "Anything with big hands, I'm into!" to the audience's laughter.
First round of the game Jake Gyllenhaal and Jimmy Fallon's slap game, Gyllenhaal won and surprisingly pulls out a giant rubber hand of his own, smacking Fallon right in the face.
Jake Gyllenhaal and Jimmy Fallon's slap game got silly fast, to the audience's delight.
At some points in the game, Fallon had to ask for Gyllenhaal's assistance in flipping his cards on the table, what with his left hand still in bandages as the host recovers from his recent microsurgery.
Fallon had recently spent two weeks in the intensive care unit of Bellevue Hospital in New York after suffering from a "ring avulsion," a finger injury that would have amputated his ring finger.
"I tripped and fell in my kitchen on a braided rug that my wife loves and I can't wait 'til I burn it to the ground," Fallon previously explained. "And I tripped and fell and I caught my fall and I'm getting up and my finger's sideways."
However, thanks to an "amazing doctor," Fallon managed to keep his finger.
"Awesome doctor, comes in with a bow tie and cowboy boots," Fallon said, to the audience's laughter. "That's my doctor! That's my guy -I knew it when he walked in."
Meanwhile, Gyllenhaal is currently promoting his new movie, "Southpaw" with Rachel McAdams.
