Will Ferrell Has Mad Drum Skills! Too Funny Not to Share! [VIDEO]

My neighbor and I were discussing whether or not Will Ferrell was actually playing the drums on this hilarious Tonight Show bit...I watched it twice and I'm pretty sure that what I heard, he really played. Plus, remember the drum set scene in the movie Step Brothers? That was probably written in because Will Ferrell is bad a** on the drums! And he's a Seahawks fan!!
