Muhammad Ali

It's not just the physical aspect of boxing, it's the whole fighter mentality that has been ingrained in me through the years as a competitive athlete. One of the hardest things you'll ever do is to box - to get into the ring and to face off with somebody whose whole goal is to knock you out, to hurt you, and to be able to fight back.

I'm not a malicious person. When you get past the tattoos and leather, I give people a fair shake. There are periods when I've sowed some wild oats, no doubt about it. And I can party with some of the heavyweights. There are some stories about me that, yeah, where there's smoke there's fire. But sometimes the smoke is just smoke.
