Can't help with the first two, but the third appears to go to the turd:
"I'm the most irresponsible person in the world. The reason I'm like that is because, at 21, you all gave me $50 (million) or $100 million, and I didn't know what to do. I'm from the ghetto. I don't know how to act. One day I'm in a dope house robbing somebody. The next thing I know, 'You're the heavyweight champion of the world.' ... Who am I? What am I? I don't even know who I am.
I'm just a dumb child. I'm being abused. I'm being robbed by lawyers. I think I have more money than I do. I'm just a dumb pugnacious fool. I'm just a fool who thinks I'm someone. And you tell me I should be responsible?"
