Jimmy Fallon has done lip-sync battles with guests such as The Amazing Spider-Man 2 star Emma Stone, but now The Tonight Show host has done his first “nip-sync” segment. Fallon and Brooklyn Nine-Nine star Terry Crews performed a duet of the song using their real singing voices.

Both Crews, known for being in great shape and extremely muscular, and Fallon were both all greased up for the duet. Fallon used a bit of help with a green screen to appear more beefed up as they sang "Ebony and Ivory,” the famous Stevie Wonder-Paul McCartney duet, E! Online reports.

Crews and Fallon (but really just Crews) made their pecs go up and down in synchronized fashion to the music, making for a hilarious television moment.

Crews recently signed on to become the new host of Who Wants to be a Millionaire. He also has a role in the film Blended, starring Drew Barrymore and Adam Sandler, which hits theaters this weekend.
