I hope I can improve. I'm far from perfect. Sometimes, I wonder what would happen if I fought myself. I think it would be a one-round KO. But if I was fighting myself, I know I could take my best punch. No, make that two rounds. I would knock myself out in two rounds.

You can’t be disturbed by anything. There’s no emotion involved. You can’t feel sorrow, you can’t feel pity, there’s nothing you feel. The job has to be done.

I know at times I come across like a Neanderthal or a babbling idiot, but I like that person.

You have to have a bunch of dimensions [of yourself]. You have to be able to adapt in this world. You can't be a nice guy living in a world of savages.

I sacrifice so much of my life, can I at least get laid?

There are nine million people who see me in the ring and hate my guts. Most of them are white. That's okay. Just spell my name right.

Every punch I threw with bad intentions to a vital area...I aimed for his ear...I wanted to bust his eardrum...Every punch had bad intentions...My record will last for immortality, It'll never be broken...I want to live forever...I refuse to lose...I would have to be carried out dead to lose...I was coming to destroy and win the Heavyweight Championship of the World, which I done.
