Justin Timberlake and Jimmy Fallon run through the History of Rap: Watch

Late Night’s "History of Rap" continued last night, as host Jimmy Fallon and guest Justin Timberlake collaborated on a fourth epic medley exploring hip-hop from its early days to current hits. 

With more than just a little help from house band The Roots, Fallon and J.T. strike B-Boy stances during "Apache"; cover one eye when impersonating Slick Rick; get a little freaky during "Rump Shaker"; and have a lot of fun imitating Busta Rhymes, Trinidad James and Eminem's unique flows

Not surprisingly, the current hit "Thrift Shop" seems to draw the biggest audience cheers. The duo cap the medley off by running into the crowd to the strains of Em's "8 MIle" anthem "Lose Yourself," which jumps back into "Apache." 

Very thorough, boys -- they even included Nelly.
