I'm really, really sad about this, but I figure, doing this kind of thing was his job-- it's what made him famous and what brought in their living.

And in this particular case, this seems like a freak accident-- much less risky than many of the stunts he did over the years. Irwin did a lot of good PR for the creepy crawly animals of the world-- he'll be sorely missed in the conservation movement. I lost a parent when I was young-- my heart also goes out to his kids and wife.
