I thought Jimmy Fallon's Emmy's opening performance  was entertaining enough last August, turns out that he got more stuff to show us.

Recently, Justin Timberlake visited “Late Night with Jimmy Fallon" to promote his latest movie project "The Social Network". The two came up with an impromptu performance when their discussion went to the History of Rap music.  After a while, the Jimmy and Justin stand up from their seats and started performing snippet of the group’s classic “Rapper’s Delight.”

Justin Timberlake and Jimmy Fallon continued performing not just one song but also snippets of Beastie Boys’ “Paul Revere,” Snoop Dogg’s “Nuthin’ But a G Thang,” Tupac’s “California Love,” Eminem’s “My Name Is,” and even Jay-Z’s “Empire State of Mind.”

Have you missed Justin and Jimmy's performance? Well, you're not alone but don't worry because you can still watch from the video below.
