He's got anger issues. Look at the way he behaves when anyone has the audacity to say no to him. Or disagrees. Or challenge him. Or if he fails at something.
Look at this fight, after the booing, Paul coming at him, and the ref screaming at him.
He lost it. He bleeping lost it. Amazing he never did a serious injury to Paul. Look at ninja warrior. He behaved like a bleeping spoilt 3 year old cos he fell off the frame.
I wouldn't let him anyway near kids, and if flappy wants to take her chances with him for a bleeping easy life, so be it.
If he does follow the MMA route, I hope someone gives him a bleeping pasting
