I used to know someone who thought he was sane.  He really did, can you believe it?  He grew up in the woods somewhere, and he went back there one time because he... had to figure something out.  But there was something about the trees, they seemed strange.  He felt like he didn't belong there any more. He hiked for days and days, into the wilderness.  He wanted to find his limits.  He wanted to see how much strength he had to keep on going.  He didn't have much.

What is flesh?  It rots away, just like the spirit.  Gentlemen, I am drunk.  Two times two is... four.  All right, so I'm not so drunk.  But I have visions of a better world!  But we must be (hic) humble. 
(violently) 
I'm not done for yet, as long as I still have my visions and I can figure out that two times... two... what a funny word that is... twwoooo!
