It was just last week that Red Hot Chili Peppers drummer Chad Smith threw down the gauntlet to his celebrity impersonator, actor Will Ferrell, challenging the Lego Movie star to a drum battle to assess who had the better skills behind the kit. Now Ferrell has accepted Smith's challenge, according to Rolling Stone, writing during Smith's recent Reddit "AMA" session, "Hi, Chad. Will Ferrell here. I saw your video and I graciously accept your invitation to a drum battle." Ferrell added, "If we can raise $300,000 for Cancer for College I will face off with you in the greatest drum vs. cowbell showdown the world has ever seen. We can do it on stage at a Red Hot Chili Peppers concert or in front of a mutually convenient public library. Your call. Also, would you rather fight a hundred duck sized ducks or one horse sized horse?" Smith told Rolling Stone a while back that he's been mistaken numerous times for the actor and recalled the first time they actually met, at a movie premiere. Smith said, "He looks me up and down and says, 'You're very handsome,' and walks away. Totally deadpan. I was like, 'You're funny. You're funny.'"
