Will Ferrell has accepted Chad Smith's challenge.

The Red Hot Chili Peppers drummer called out the actor and challenged him to a drum competition.

During Smith's Reddit AMA, Ferrell accepted the challenge.  Will 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 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?"

Ferrell and Smith have been connected for years because they look a lot alike.  So, this is exciting.

Other highlights from Smith's AMA included an answer about a 1991 run of concerts that featured the Red Hot Chili Peppers, Nirvana, and Pearl Jam:

"Pearl Jam was the opening act, Nirvana was right after them and it was on the West Coast, and we did some dates from right after Christmas through New Years, 1991. And it was right when Nirvana was blowing up, and some of the most incredible crowd energy I felt watching them during the Nirvana set. They would start "Teen Spirit" and the place would go fucking bananas. You would feel everybody levitating off of their feet. Really something."

Smith also said that Blood Sugar Sex Magik is his favorite Chili Peppers album.  He called working with Johnny Cash, "One of the highlights of my life.'  If he could play with any other band, he'd choose Led Zeppelin.

He also shared this in regards to the future of rock music, "As long as there's somebody in their bedroom listening to the blues, because Rock n' roll is based on the blues, I am hopeful and confident that someone will come up with a new and creative way to present their ideas and someone will do that. And I'm hopeful it's within my lifetime."
