There’s very sad news today from Australia. Steve Irwin – who the world knew as “The Crocodile Hunter” — was killed by a stingray while filming a special in the waters off an Australian island. Irwin was enormously entertaining, informative and one of the great showmen of the age. His typical shows — with crocs, snakes and other truly dangerous critters — often showed how dangerous his work was. But Irwin was a man’s man, shrugging off injuries and making sure the show went on despite whatever wounds the creatures inflicted on him. This time, bad luck proved fatal. The stingray’s barb apparently hit him directly in the heart. Thanks, Steve. You were one of the greats. Crikey, we’ll miss you.
