Ladies and gentlemen, prepare yourselves to be wowed once again by Jimmy Fallon and Justin Timberlake, as they take you through a rap-fueled voyage.

The funnyman duo did History of Rap so good the first time, they had to give it a part two while Timberlake was on Late Night With Jimmy Fallon on Tuesday, busting out another whopping medley of countless rap songs. All with the backing of The Roots who cranked through a myriad of beats, Jimmy and Justin rhymed and posed their way through old school (Public Enemy!), new school (Lil Wayne!) and everything in between (Cypress Hill!).

Timberlake could barely contain his laughter as he did the chorus from Nelly’s “Hot in Here,” and there was even a little “Teach Me How to Dougie” thrown in for good measure.

JT is on the promotional trail for his new movie, Friends With Benefits, which comes out on Friday, July 22. Check out the trailer here:
