Jimmy Fallon & Justin Timberlake did "The History of Rap Part 4" on Late Night With Jimmy Fallon Friday night and those 2 white guys got down!

From the start, they did "Jump On It" and continued with Timberlake's Fat Boys beat boxing riff, to RUN DMC, Beastie Boys and LL Cool J classic cuts.

They went into the 90's with 2 Live Crew, Teddy Riley's Wrekx N Effect, Salt N Pepa, Snoop Dogg, Busta Ryhmes, Notorious B.I.G., Jay Z, Nelly, and more.

When they went the 2000's, they brought to the front Chamillionaire, Waka Flocka, and Macklemore & Ryan's Lewis "Thift Shop" back to Eminem's "Lose Yourself" to close out the set. Interesting they chose 2 white rap acts to end it. Hmm.
