George Knapp is on the road to recovery. He just tweeted "More cowbell".
Yep, more cowbell is the answer to everything.

I hope he's on the mend, but imagine how cool it would be if those were someone's last words? When I finally shake off this mortal coil and join the choir invisible, I swear I'm going to try to make 'More cowbell' my last words. That'll give 'em something to chew over.
