When Justin Timberlake does late night television, great things generally occur, and last night's appearance on NBC's 'Late Night with Jimmy Fallon' was no exception, as the dynamic duo of Justin and Jimmy joined forces once again for a second installment of their 'History of Rap' song.

Though feigning hesitance, due to the success of their first routine back in September, a reluctant Justin and Fallon hit the stage, at the crowd's goading, to run through a list of some of hip-hop's greatest party songs.

Bookended by Kurtis Blow's seminal 'The Breaks,' J and J tore through two dozen karaoke standards by N.W.A., Public Enemy, Rob Bass & DJ EZ Rock, Salt-N-Pepa and Vanilla Ice (which received a resounding cheer from the audience) into Black Sheep (which didn't), before heading into new territory with Lil Wayne's 'A Milli, DJ Khaled's 'All I Do is Win,' Cali Swag District's 'Teach Me How to Dougie,' (with accompanying dance) and an ominous, tuba-powered take on Rick Ross' 'B.M.F.'

Just past the five-minute-mark, the pair jumped into the audience, to rock a crowd-favorite rendition of Biz Markie's 'Just a Friend,' and concluded the bit by returning to 'The Breaks,' rapping "Clap your hands everybody, if you got what it takes/ 'Cause I'm Justin, I'm Jimmy and we want you to know that these are the breaks!"

Do you think Jimmy and Justin's 'History of Rap 2' topped the first?
