Will Ferrell is preparing to face-off against Red Hot Chili Peppers star Chad Smith in a drum battle to raise funds for charity.
The American rocker threw down the gauntlet for a musical duel in an online video after Ferrell made light of the resemblance between himself and the musician during a question and answer session on Reddit.com.
The Anchorman actor responded to the challenge during another Ask Me Anything session, agreeing to take part if they can raise $300,000 (£187,500) for a cancer charity.
Ferrell plans to take on the drummer using a cowbell he made famous during a Saturday Night Live skit.
He writes, "Hi, Chad. Will Ferrell here. I saw your video and I graciously accept your invitation to a drum battle. If we can raise $300,000 (£187,500) 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 then taunted his rival with some light-hearted banter, replying, "I think Mr Ferrell is a delusional imposter. It seems to me that he has gone off his meds (medication) and he needs to seek professional help because I am obviously more talented and handsome than he is. You know, his cowbell work is well-documented, but his drumset skills are nominal based on Step Brothers the film. Other than wiping his testicles on the drums, which of course I give high marks to".
The challenge will go ahead once the pair raises enough money for Cancer For College, a charity that offers college scholarships to cancer sufferers.
