Will Ferrell and his "twin" Chad Smith of the Red Hot Chili Peppers have a drum-off! The battle stemmed from a Reddit session where Ferrell was asked about his resemblance to the RHCP time keeper ("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 exchange escalated until it became a full-blown challenge with $300,000 in proceeds going to Cancer for College. The duel happened last night on Tonight Show with Jimmy Fallon.
