i love dave grohl!!!! he is my personal hereo, not only is he the drummer from nirvana, foo fighters front, as you mentioned but he is also in queens of the stone age, which i have become a big fan of. he's so amazing. i was reading this thing that kurt cobain wrote and it was just how dave was so amazing and cool and such a funny guy when you see him in interviews. i love it!
Yeah, the humor thing is what is awesome about the Foo's as a whole. If they weren't musicians, they would all be great comedians
