Additional proof (as if we needed any) that Dave Grohl is one cool mother trucker. As if being in one of the biggest bands in the world is not enough, the mulit-talented rocker appeared on 'The Muppets' last night!

Grohl threw down on an epic drum battle with Animal. Yesterday 'The Muppets' - tomorrow a Foo Fighters cartoon? Anything is possible! #grohlforpresident
