Mike Tyson's life story is the gift that keeps giving.

And giving. And giving.

At one time he was the baddest man on the planet, a heavyweight champion who terrorized anyone who got in his way, inside the ring or out. More recently he's unburdened himself as perhaps the most tortured soul on earth, with a one-man show on Broadway that Spike Lee has turned into an HBO special airing Nov. 16.

Now he's got a new autobiography that might be the most soul baring book of its genre ever written.

The title is "Undisputed Truth," and the truth is that Mike Tyson is one messed up dude. He's desperate to put his demons to rest, but the book needed a new chapter to show that he can't.
