cracker jack

A game where several men gather around a cracker (I always picture a stoned wheat thin) and furiously masturbate onto it. Whoever ejaculates first wins. By a similar token, the loser is he who ejaculates last. The loser must consume the cracker as a penalty for sloth.

I got the clap from losing a game of cracker jack in college.

Kangaroo Jack 

The worst movie in the history of the universe. I would not see this movie if you paid me $1,000,000 AND gave me a monkey. When I saw this movie I was praying to see That Darn Cat.

"Kangaroo Jack took up an hour and a half of my life, and I want it back."
