Good Nature Shows on DVD?

I'm looking for a prez for my GF... she likes funny nature shows, y'know not dry serious ones but zany goofy ones, like Jeff Corwin and Wildboyz (the Jackass guys). Basically ones that show the wildest craziest animals with a funny host. Are there any other ones like that on DVD?

The only other one I saw was Jack Hanna but that didn't look terribly entertaining...

 

Try Steve Irwin the Crocodile Hunter. I hear the episode with the stingrays is a real killer.

 

If you can find it, get this:

It's really good, if fictional, done in the style of the programs you listed.

ETA: This is a good one too: http://www.amazon.com/Chased-Dinosaurs-Nigel-Marven/dp/B00017LVSM/ref=pd_cp_d_1
