Prime Time Amusements is clearly thinking that Kimbo is still a money maker, because they're selling this incredibly awesome Team Kimbo Boxing Machine.
This life sized arcade game features Kimbo Slice, and allows players to match up their speed and strength against one of the best glass jaws in semi-pro MMA.
If you really want to fight Kimbo, you can probably just find him somewhere on the streets of Miami and wave a $50 bill in front of his face. Well... now that he's a little more famous, it might take $100 or so to get him to fight. He's a little less desperate than he used to be.
But if you want to get the experience of fighting Kimbo, this is definitely the way to go. The game allows you to test your skills for an entire round, but if you're anything like Seth Petruzelli, you should be able to beat the game in about 14 seconds. In case you didn't see the fight, that's the high score for this game.
Here are a couple more angles, for further evaluation:
And in case you need a bit more of a challenge, I suggest the McDonalds version. Grimace might be able to give you a bit more competition than Kimbo "14 Seconds" Slice.
