Leave it up to Justin Timberlake and Jimmy Fallon to school us on what it means to drop some bars. Earlier this week, JT took to "The Tonight Show Starring Jimmy Fallon" for the sixth installment of their musical medley "History of Rap" bit, and it was a everything a hip hop head could have asked for.

The twosome kicked off the six-minute medley with N.W.A's "Straight Outta Compton," but the pop titan had to jokingly warn the host to not get too carried away. "We went through this before. You are not straight outta Compton. You are straight outta upstate New York," he said. 

JT and Jimmy went on to cover some of the biggest hip hop classics from past and present, including Drake's "Know Yourself," Salt-N-Pepa's "Let's Talk About Sex" and Big Sean's "I Don’t F*** With You."

After all the shenanigans were over, JT sat down to chat with the host about Silas, his 5-month-old son with wife Jessica Biel. "It is the most insanely amazing, most beautiful, unbelievable thing that can ever happen to you," he said about fatherhood.  

Later on, the guys took to the U.S. Open and goofed around to Beyoncé's "Single Ladies" because that's what celebrity best friends do. Watch the video below.
