For much of his career, Ferrell has been saddled with the gift and the curse of looking exactly like Chad Smith, drummer for the Red Hot Chili Peppers. This has resulted in a playful rivalry between the two men, with Ferrell pretending to be Smith after a recent Reddit AMA. Smith didn't take the insult lying down, challenging the comedian to a musical duel – drum vs. cowbell – all in the name of charity.
Ferrell accepted the challenge, and after the pair raised $300,000 for Cancer for College, the duel was on.
Instead of high noon at the town square, Ferrell and Smith faced off at high midnight on the Tonight Show. Who came out on top? Well, you'll just have to watch the video above. And if you want more cowbell, well, we've included that below.
