VIDEO: Justin Timberlake and Jimmy Fallon Perform the 'History of Rap Part 2'

If you couldn't tell from the trailer for Friends with Benefits -- which features star Justin Timberlake singing not one, but two cheesy one-hit wonder classics ("Jump" by Kris Kross and "Closing Time" by Semisonic), the former N'Sync'er loves toying with his musical past. Couple that with the fact that the last time Timberlake appeared with Jimmy Fallon on Late Night, the pair performed "The History of Rap," and it shouldn't be a surprise that a sequel was in the offing. No "Jump," unfortunately, but there was Biz Markie. Click through to watch the video everyone will send you before lunch.

Timberlake is nothing if not COMICALLY charming. Friends With Benefits is out Friday.
