Terry Crews and Jimmy Fallon "nip-sync" on "Tonight Show"

You've seen Jimmy Fallon sing on "The Tonight Show" before, but you've never seen it quite like this.

Fallon and guest Terry Crews performed a "nip-sync" on Monday night to the Stevie Wonder/Paul McCartney classic "Ebony and Ivory," moving their oiled-up pecs along with the music.

It should be noted that while Crews ("Brooklyn Nine-Nine") was actually shirtless for the performance, Fallon had a little help from a buff body double.

Crews is the new host of "Who Wants to be a Millionaire" and stars in the Drew Barrymore/Adam Sandler film "Blended," opening this weekend.
