Jimmy Fallon And Justin Timberlake Perform 'History Of Rap Part 2' (VIDEO)

The last time Jimmy Fallon, Justin Timberlake and The Roots performed "History of Rap," it became an immediate viral smash, and one of the early indicators that "Late Night with Jimmy Fallon" was going to be something to watch out for. So obviously NBC did the logical thing and had it pulled off the web within a few months. (In fairness, the royalties for that one must not have been cheap.)

But thank goodness Timberlake has a new movie to promote, because that means we were treated to another medley of hip-hop biggest hits and most influential beats. This time around, samples of everyone from Salt-n-Pepa to DMX to Cali Swag District are represented.

Be sure to check this one out before it's inevitably removed from the web!
