Last week it was pretty hilarious when the similarity in looks between Will Ferrell and Red Hot Chili Peppers drummer Chad Smith was brought to light in a Reddit Ask Me Anything session. As a result, Smith decided to challenge Ferrell to a drum battle, and now Ferrell has responded, in the condition that it's for charity.

In a separate AMA hosted by Smith, Ferrell chimed in: "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 (£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?"

Smith shared his opinion in the AMA as well: "I have to comment that I think Mr. Ferrell is a delusional imposter. It seems to me that he has gone off his meds 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."

We'll see when the battle could possibly go down. If Ferrell channels some of his Ron Burgundy and jazz flute intuition, it could be pretty brutal.
