Yesterday I watched the best documentary. It's called Hands on a Hard Body, and it's about this contest in East Texas where 24 people are in a contest to win a truck. Everyone starts off with a hand on the truck. The last person left touching the truck wins it. There are short potty breaks every so often. It lasted for 4 days. Completely ridiculous.
Go find it and watch it. It's funnier than a Christopher Guest movie, and it's real. I have a copy on VHS. Borrow it from me or find it elsewhere, I commend you!
