It's on! Comedian and actor Will Farrell has accepted a drum-off challenge from Red Hot Chlli Peppers sticksman Chad Smith.
Smith challenged Ferrell to cross sticks and pit paradiddles last week when Ferrell remarked on the uncanny similarity in looks between him and the Chili's man.
The Anchorman star has now accepted the offer, on the provision that they raise money for a cancer charity.
Ferrell's reply came during an online chat hosted by Smith. "Hi, Chad. Will Ferrell here. I saw your video and I graciously accept your invitation to a drum battle," wrote Farrell.
"If we can raise $300,000 (£182,000) 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?"
