VIDEO: Terry Crews and Jimmy Fallon Had A Nip Sync Battle on 'The Tonight Show'

Because the world is a place that's rich with the fabric of surprise, Terry Crews appeared on The Tonight Show last night to have a nip sync battle with Jimmy Fallon.

For the uninitiated, which is all of us since this is a concept that was apparently invented and birthed unto the world last night, a "nip sync" involves dancing pecs that move in rhythm with a song. In this instance, the song was the 1982 Paul McCartney and Stevie Wonder hit, "Ebony and Ivory." And, because not everyone can be in pec-tacular shape all the time, Jimmy's pecs are supplied by an exceedingly buff model (since the whole "dancing pecs" thing is harder than it looks....um, I imagine).
