Let's talk about sex.

Last night on The Tonight Show, perennial BFFs Jimmy Fallon and Justin Timberlake released the latest installment in their entertaining History of Rap medleys. The world "history" is used a little liberally though, because they sing Big Sean's “I Don’t F*** With You,” which came out in 2014. 

Jimmy and Justin cover everyone from NWA, Salt-N-Pepa, Wu-Tang Clan, Jay z & Kanye West, culminating with them "fighting for their right to party" in the audience.
