Watch Jimmy Fallon and Terry Crews 'Nip-Sync' a Shirtless Song

We've seen Jimmy Fallon and Emma Stone do lip-sync competitions. But that's nothing compared to nip-sync competitions.

Last night on "The Tonight Show Starring Jimmy Fallon," Jimmy had Terry Crews of "The Expendables" and "Brooklyn Nine-Nine" in as a guest. Naturally, Crews had to get shirtless and flex his pecs at some point, since he made it big doing just that for those crazy Old Spice commercials. But we would have never expected Fallon to join him.

In the video, a shirtless Crews and a (digitally assisted) shirtless Fallon did a "nip-sync" to "Ebony and Ivory." And it was absolutely beautiful.

If you're wondering why Crews is such a beast, his background will shed a little light: He started as a pro football player, but left the league and started to pursue jobs in the entertainment industry. But from the sound of it, one of his first TV jobs wasn't much safer than football.

"They'd put me into a cage that was kind of built like a Coke can, and then they'd set the ends on fire and open up the cage and take a crane and lift us into the cage," said Crews in his interview, describing his "American Gladiators"-like game show "Battle Dome." "The whole object of the game was that each contestant had to get me out of the cage. Needless to say, I didn't want to go. It was a brutal battle that was a lot of fun."

Thankfully, all he has to do these days is sing and flex. Check out the hilarious video below:
