I always enjoyed Irwin’s show as well. He was both entertaining and informative.
According to one of the stories I read on Steve Irwin’s death, this was almost a “freak” occurence in that stingray stings are very painful, but almost never fatal. In this case, the strike hit him directly in the heart, and probably killed him instantly.
Not to compare the two men, but the news of the croc hunter’s demise was no more surprising to me than was the news that Timothy Treadwell was eaten by a grizzly. In both cases, you knew something like this was going to happen. The difference between the two men is that Steve Irwin understood the risks and the nature of the animals he worked with, but was fearless almost to the point of insanity (which was part of his entertainment value), while the “grizzly man” had some serious delusions about the natural world, and his role in it.
