Jimmy Fallon and Justin Timberlake are at it Again With History of Rap 4! [VIDEO]

Jimmy Fallon and Justin Timberlake are the new Dynamic Duo....forget Batman and Robin, these guys are the new super heroes of today Yo! Here we go The History of Rap 4.

We all know that Justin Timberlake has mad skills, but Jimmy Fallon, you go boy! One can only hope that these guys put a compilation c.d. together and all the profits go to charity. Of course they must have Jimmy's back up band The Roots to make it all complete.

This may be my favorite one of them all with Old School meets New School covering it all. My favorite part is Justin Timberlake cracking up during a few of the songs, and of course I could not help but notice that gold band on his ring finger.
