I know he's retired, but I'm a big fan of Shaquille O'Neal, his game and his personality. I have a pair of his shoes in my office. You see the size of his shoe and think, 'This is not real, this couldn't belong to a human being.' But he is human!

I don't like to get hit, who likes it? I probably wouldn't do this sport if I was getting hit that much.

There are 49 guys that got bored to sleep on my record, so they got knocked out by it.

My brother is a doctor and he will take care of post-traumatic stress. I think he'll do it for free.

That's the most terrible mistake you can make: to relax. It's difficult to become a champion, but it's more difficult to maintain it for many years because you're getting too comfortable.

I'm playing right now a role, and the role is called the 'Heavyweight Champion of the World.' And it takes all of the time. And I love this role, and it takes a lot of attention for me for the sport, and I just don't want to lose the title, so that's why I have to stay focused and not become an actor.

Sometimes it's boring because it takes time, but it's enjoyable. So beating up people for a living is really fun.
