Last night, a mustachioed Jimmy Fallon got a big surprise when an unexpected guest popped in to freestyle with Tonight Show house band The Roots: the only and only Dave Chappelle.
The comic made a special appearance during last night's "Freestylin' with The Roots" segment -- when Fallon went to find a random audience member to participate, the stand-up stood up, surprising everyone including the host.
Chappelle was there to plug his upcoming August shows at New York City's iconic Radio City Music Hall - and, also, to get a song written about him by The Roots, who riffed on his superpower: "disappearing for long periods of time."
