Mike Tyson announced today he's "tired of being stupid" and will make his latest comeback bid on February 22 next year against Clifford Etienne in Memphis, Tennessee. He was the undisputed bad boy of boxing, but at a press conference in Memphis announcing his latest fight, Tyson said he's ready for a complete personality makeover. "There's so many things, my whole barometer and perspective has had to be changed - in a positive direction, that is. And it's just an ongoing process. I feel good. I'm just very happy. I'm tired of being stupid, I'm just ready to go," he remarked. Tyson will take on Etienne at the Pyramid Arena - the same venue where Lennox Lewis scored a devastating eighth round knockout over him in June this year. Tyson had behaved remarkably well at the end of that fight and perhaps that was a sign of things to come. "I'm blessed to be Mike Tyson, where I've been fortunate enough to make a lot of mistakes and still be able to just come back from when I was totally decimated in my life. I just feel so much good about my transformation and just becoming a decent human being. I'm just happy, man, hell! Let's fight, I could do that very well with a clean conscience," said the boxing star. The new and reformed Tyson wasn't the only surprise at the press conference. There was also the new and reformed Tonya Harding - announcing a career switch from skating to boxing. "It is my goal to be a future undisputed bantamweight champion. My proven athletic ability, as you all know, and competitive nature, will help this become a reality," she said. That proven athletic ability and competitive nature was of course highlighted when Harding was banned from skating for organising a vicious attack on her rival Nancy Kerrigan. But now at least the violent streak could take on some legitimacy in the boxing ring.
