Will Ferrell and Chad Smith Have a Drum-Off On "The Tonight Show"

Will the real Chad Smith please stand up?

Will Ferrell and the Red Hot Chili Peppers drummer faced off an epic drum battle on Thursday's "Tonight Show."

The duo has been told that they look alike for years, and the actor first mentioned the idea of a drum battle during a Reddit AMA in February.

"It has been acknowledged many times that myself and Chad Smith, drummer for the Red Hot Chili Peppers, share a resemblance to each other. A lot of people think that it's me playing for the Red Hot Chili Peppers. But that would be an insult to Chad Smith. The truth of the matter is there is no Will Ferrell. Only Chad Smith." The drummer replied, writing, "Stop impersonating me. In fact, I need you...drum battle." He added, "Me and you. I've seen your skills; you don't got 'em. Let's go. Golden cowbell. Winner. Boom!"
