Boxing: Tyson: he's back, but why?

The last time Mike Tyson was at a press conference to publicise a fight with a Briton, an embarrassing fracas erupted which resulted in defending World Heavyweight Champion Lennox Lewis decking 'Iron Mike' with a knuckle sandwich and Tyson scrambling on all fours like a rabid animal trying to bite another chunk out of the champ's upper thigh.

But when Tyson came face to face with Lewis's London neighbor Danny Williams on Tuesday (picture courtesy Showtime/Tom Casino) to publicise their July 30 ten rounder at the Hall Arena at the Kentucky Fair and Exposition Center in Louisville, Kentucky, the former two-time world champion was all smiles, jokes and hugs.
