Justin Timberlake dropped by The Tonight Show on Wednesday (9/9/15) and dropped some beats with longtime friend and host Jimmy Fallon, for the sixth installment of their "History of Rap."

Because who better to school us on hip hop anthems than a couple of nerdy white guys, amIright?

The besties opened the show cold, performing a medley of 25 classic rap songs from the 1990s through the present. Among them, Salt-N-Pepa's "Let's Talk About Sex," MC Hammer's "U Can't Touch This" and DJ Jazzy Jeff & the Fresh Prince's "Summertime."

Later, Timberlake sat down for an interview with Fallon and discussed being a new dad. "I have trouble wiping my own a**," Justin joked about caring for his five-month-old son Silas Randall, before describing fatherhood as, "the most insanely, amazing, most beautiful, unbelievable thing."
