Do not talk about Fight Club.
DO NOT talk about Fight Club! 
If someone yells “stop!”, goes limp, or taps out, the fight is over. 
Only two guys to a fight.
One fight at a time, fellas.
The fights are bare knuckle. No shirt, no shoes, no weapons. 
Fights will go on as long as they have to. 
And the eighth and final rule: if this is your first time at Fight Club, you have to fight.
