I just came on to GT with the intent of informing you all of this very same sad news, but as always, I have been beaten to it.
Sad as it is, you have to laugh at the irony. The guy made a living out of basically teasing huge crocodiles and poisonous snakes. He always got out of it unharmed. He goes for a swim one day, and a stingray sticks a barb through his chest.
Kinda like that guy who went over Niagara Falls in a barrel, made it out alive, then slipped on an orange peel and died.
