Colorful former boxer Mike Tyson admitted to ESPN's Rick Reilly that he got a prison guard pregnant - while he was in the prison.

Oh, yeah. In prison, stuff happens, Tyson said about getting a prison guard pregnant. But she had no baby.

Tyson recalled the tale as something he left out of his two-hour, one-man Las Vegas show. During the show Tyson detailed his past with hookers, boxing promoter Don King, ex-wife Robin Givens, and his problems with drugs, according to Reilly.

Sometimes, according to Tyson, he would get hooked up to a morphine drip just for the pleasure of it.

I just liked morphine, he told me, but I had to take a lot of it because it didn't stay in your system for a long time. ... And I'd have my cocaine, and I had my marijuana, and I had my Cialis and Viagra and my little friends all sitting there. That's just how I lived my life.

Tyson, known as having one of the hardest punches in boxing history, was also unafraid to talk about infamously biting off a piece of Evander Holyfield's ear in 1997. Tyson was struggling during the fight before he decided to bit off a small piece of his ear and was shunned for the disgusting behavior.

They sent me to the Mayo psych clinic, he told the crowd. A nuthouse. And there was this little white lady in there, looking at me. She looked like Thelma from Scooby Doo. She asked me why I was in and I said, 'Aw, these people think I'm crazy 'cause I bit a guy in a fight. But he wouldn't stop head-butting me!' She said, 'Oh, you was in a fight!' I was so grateful she said that. She made me feel like a human being again.

The one-man show is entertaining, according to Reilly, but does have its downfalls.

It wasn't exactly Sinatra at the Sands, Reilly wrote. There were too many times you couldn't understand him, or he'd KO the language (I had my mother's coffin resumed), or he'd murder songs, turning the night into a kind of a Cirque du Sore Ears. But if you could abide all that, you were rewarded with gold nuggets.
