It's been more than 70 days since Josh Topolsky and Jimmy Fallon took the stage together for relevant irreverence. Those were much simpler times. Now it's future Tonight Show host Jimmy Fallon and his future Tonight Show band The Roots.

Jimmy's "organic guests" include future Google intern Vince Vaughn, stand-up comedienne Amy Schumer, and Major Lazer! While you wait, check out Josh, Jimmy, the Oculus Rift, and codpieces:
