Justin Timberlake & Jimmy Fallon's Amazing 'History Of Rap' Medley (VIDEO)

The audience of "Late Night With Jimmy Fallon" got a special treat last night when guest Justin Timberlake performed a thorough "History of Rap" medley with Fallon and The Roots.

After talking about "The Social Network," Timberlake noted how lucky Fallon is to have The Roots as a house band, prompting them to reminisce about other hip hop legends like The Sugar Hill Gang.

The conversation quickly broke out into a full-fledged medley of the most memorable rap songs in history, from Dr. Dre to The Dream, culminating with a spirited verse of "Empire State Of Mind" with the audience.
