The tomfoolery Mirko Cro Cop has been involved in since he 'retired' from MMA is astounding. It's also important to note that five fights later, Cro Cop is the most active retired fighter in the entire combat sports industry. Now it even looks like he's taken the role of referee, fight doctor, judge, and promoter in his own variation of backyard brawls. The apparent rule in Cro Cop's events is that you must be over the age of 50 and you can only wear one boxing glove. The rest is up to the fighter -- consuming alcoholic beverages is encouraged, however. Check out this clip from a bout between two guys. Don't worry, it ends in a remarkable KO. Props to Gonzo for the +100 news tip.
