I Need More Cowbell

You would too if you feel pissed and crappy.  Hence this.

The second take is just funny as hell.  With Walken's deadpan expression, Ferrell's dancing, and of course, the cowbell.   Easily SNL's best skit.

I wonder where that expression came from though, picturing hell as funny.

Right.

I got a fever.
