MIKE TYSON bares his soul in his autobiography, "Undisputed Truth," that will be released Tuesday. It's not pretty.
The former heavyweight champion is desperate to put his demons to rest, but the book needed an extra epilogue written just before printing to talk about him falling off the sobriety wagon once again.
"Sometimes I just fantasize about blowing somebody's brains out so I can go to prison for the rest of my life," he writes. "Working on this book makes me think that my whole life has been a joke."
Though he has reinvented himself in recent years as a family man, he says he lives daily with the dark past of a junkie who loved to snort cocaine and drink and was constantly preoccupied with finding women to bed.
