I guess I agree with ya about Steve Irwin....I used to enjoy his shows, but they've just gotten to the point of being about his silly catch-phrases and his Bindy too much for me, I guess.
I too spent my childhood watching Marlin Perkins.....I think he will always be THE host. It was a family thing, we'd all watch together on Sundays, or if something else was going on, at least my Dad and I never missed an episode, lol......
I think too many of the shows today are more about just "entertainment" than actually learning about the creatures they are showing....if you understand what I mean.
Corwin IS kinda cute though.
