from the eponymous book by chuck palahniuk, the Seven Rules of Fight Club:
1. you don't talk about fight club
2. you don't talk about fight club
3. two men per fight
4. one fight at a time
5. no shoes no shirt
6. fights go on for as long as they have to
7. if this is your first night at fight club, you have to fight.
sounds a little like real life at times, doesn't it?
