Mike Tyson has never played 'Mike Tyson's Punch-Out!!'

Mike Tyson took part in a Monday conference call to hype his nationwide one-man stage show, "Mike Tyson: Undisputed Truth." The ex-heavyweight champion and baddest man in the planet, once destined to burn out and fade away, is today a stunning tour de force of redemption.

He has a new charity aimed at helping kids who fall in between the cracks, and will spread the word about his newfound stability and sobriety and humility starting Feb. 12, when the 10-week, 36-city tour kicks off in Indianapolis. Tyson did a dry run in NYC, on Broadway, in late summer, and reviews for the show, co-crafted with Spike Lee, were almost uniformly positive.

The most stunning revelation for me during the call occurred when the ex-fighter, age 46, admitted he'd never played the "Mike Tyson's Punch-Out!!" video game, because he took up gaming years after that game came out.

Humility and candor are what Tyson is about these days. When asked for one thing he might do differently if he could hit the life rewind button, he said, "I maybe wouldn't sleep with as many women." The recent shooting death of Hector "Macho" Camacho touched him, and had him shaking his head, wondering why he hadn't met the same fate, back when he was so reckless and surly that he'd get drugs from dealers and then refuse to pay them.

There were glimpses of the "old" badass: Tyson said that he does get heckled, and who knows, one night, depending on his mood, he might leap into the crowd and greet the heckler.
