When: 1998

It's not a great idea to anger a convicted rapist who's famous for biting a man's ear off. Don King learned this lesson the hard way. When Mike Tyson discovered more than $20M in missing assets, he tracked down Don King and beat him into the pavement outside a Los Angeles hotel.

Iron Mike said in the film Tyson that he was triggered by King's refusal to admit any wrongdoing, "I confronted him. He basically denied it and I attacked him in front of these old decrepit white women." Tyson would go on to say of King, "he's a wretched, slimy, reptilian motherfucker...he would kill his mother for a dollar."
