"Tonight Show" host Jimmy Fallon likes to sing with his guests, so it's not all surprising to see him do a duet of "Ebony and Ivory" with actor Terry Crews.
It's how they did the 1982 Paul McCartney-Stevie Wonder song that you have to see to believe.
It's worth noting that Crews, the heavily-muscled NFL player and star of the Old Spice commercials, is doing all his own body work here. Fallon, on the other hand, has a nipple double, with his head digitally imposed on the body of someone who probably never gets mistaken for for the "Tonight Show" host.
Crews was promoting his work in the new movie "Blended" with Drew Barrymore and Adam Sandler, which hits theaters on Friday. He's also starring in the TV comedy "Brooklyn Nine-Nine" on Fox and is set to take over as host of "Who Wants To Be A Millionaire?"
