Jimmy Fallon and Justin Timberlake had a few more lessons to cover, so they came back to present the History of Rap Part 2.
Earlier this week, Justin dropped by "Late Night with Jimmy Fallon" to promote Friends with Benefits. While he was there, Justin and Jimmy couldn’t resist the chance to school the audience on rap, yet again.
The question is, could they top their first karaoke session? Watch the hip-hop mashup below and tell us! While it’s always funny to watch these two rap, Justin’s dance moves are pure comedy.
In case you missed the original, which aired last September, check it out below. Justin and Jimmy do a decent cover of Snoop Dogg. They even got the audience in on the act!
