Jimmy Fallon and Justin Timberlake Bring 'The History of Rap' to 'The Tonight Show'

Jimmy Fallon may be the host of The Tonight Show now, but he's basically doing Late Night at 11:35 p.m. That couldn't be more apparent when Justin Timberlake was his guest on Friday night. After introducing Timberlake as "a friend of the show" (you know, the show that's only on its fifth episode), Fallon and Timberlake launched into "The History of Rap 5." This was the first time Fallon and Timberlake performed a new "History of Rap" since last March.

We're definitely living in a new Tonight Show era, folks. I could be wrong, but I don't think Jay Leno ever rapped the words "move, bitch, get out the way."
