Justin Timberlake stopped by The Tonight show Starring Jimmy Fallon and you know what that means. Rap school is in session once again.

The two started the show with another medley of hip hop classics for the sixth edition of “History of Rap.” The two ran from R. Kelly and LL Cool J to Fetty Wap and Kendrick Lamar. They stopped by N.W.A. to give a shout-out to Straight Outta Compton, threw in a sidebar about sex courtesy of Salt-N-Pepa and fought the power with Public Enemy.

The medley kicked off with R. Kelly & Jay Z’s “Fiesta” and finished with The Beastie Boys’ “Fight For Your Right.” Other songs in between included LL Cool J’s “Friends,” MC Hammer’s “U Can’t Touch This,” “Mo Money Mo Problems” by Notorious B.I.G. and “Know Yourself “by Drake.

While it feels like Timberlake and Fallon do this way too often, it’s actually the first “History of Rap” since the fifth edition in February 2014.

Timberlake also shared a picture of Silas, his first child with wife Jessica Biel.
