Jimmy Fallon and Justin Timberlake Hit Us With 'History of Rap, Part 2' (VIDEO)

Hey, remember that one time when Justin Timberlake and Jimmy Fallon did a rap medley called the "History of Rap" and it went viral and everybody loved it? Well, they're doing it again.

Timberlake was on "Late Night with Jimmy Fallon" to promote the upcoming release of "Friends With Benefits" when Fallon brought up the idea of doing another "History of Rap."

Timberlake was hesitant..."We can't do it again, we can't top--" started Timberlake, but then the audience erupted into applause. Timberlake and Fallon shrugged, grabbed a couple of microphones, and started on their new medley that includes "The Message" by Grandmaster Flash, "Push It" by Salt n Pepa, and even a little bit of "Ice Ice Baby."

As always, the two are totally entertaining. Check out the video below:
