Earlier this year we reported that Will Ferrell and his doppelganger, Red Hot Chili Peppers drummer Chad Smith, had agreed to a drum battle. Now it appears that the date for this epic face-off has finally been set—May 22 on The Tonight Show Starring Jimmy Fallon.

The idea was first raised back in February, when Ferrell told a Reddit AMA, “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.”

Smith responded to Ferrell’s claims by challenging the comedian to a drum battle. Ferrell said he was down if the duo could raise $300,000 for the charities Cancer for College and Little Kids Rock, and the goal was easily met via an online fundraiser.
