Check out this video, here is the info some guys also post at the Darkfall forums: Kimbo Slice vs Sean Gannon
Explanation: Kimbo (the black guy)is a Florida professional street fighter. For $5000-$10000, he'll meet anyone anywhere and fight him. At least that's what he claims. Sean Gannon (the white guy) is a cop who wants to be an MMA fighter. Kinda like what you see on the UCF (UCW? Something like that).
Gannon wanted to fight Kimbo so they set up the fight though Kimbo wanted rules so they signed a contract for simple fisticuffs, no submission holds, no groundwork. Gannon, not a boxer, still agreed to the rules. You need to know this to understand what all the screaming and shouting is about.
Who broke the rules first and did it make a difference?
Afternote: Gannon got a sanctioned UFC fight later (b/c he's a cop, i.e. a novelty act) and got waxed in about 90 seconds.
