All animal show hosts are insane.

Example 1: Steve Irwin, the Crocodile Hunter. Ummm... Enough said.

Example 2: Jeff Corwin. Makes toads do yoda impressions and pretends to eat poison dart frogs. Also tends to play his own insane cousin and run from himself. Sometimes amusing, sometimes...just...weird. Quote from tonight's episode as Jeff is talking to his camera crew and using a stick to handle a large rattlesnake: "Guys, you might want to get back unless you want him in your lap."

Example 3: Ruud of Bugging with Ruud. Tonight he looked at dangerous bugs in Australia. Any ant species that he encountered was encouraged to climb on him and bite him. One species (weaver ant) sprayed formic acid in his eyes. He rather regretted the very last ant (I forget the name, but it was a type of bull ant and the largest ant in Australia, getting to be over an inch long). He yelped at each bite, and was in tears even after he'd gotten them all off. On the bright side, he used an aboriginal herb to make it hurt less (some sort of fern). Then he said something like, "Oh, much better," looking very relieved. "Now it just feels like an ordinary bee sting." On the bright side, he did not encourage venomous spiders to bite him, but was rather cavlier in handling them (including the notorious Sydney funnel web).

Any I've missed?
