I've actually seen Bear Grylls (the guy on Man vs. Wild) do the same thing you just mentioned.

You're right though KA some of the things he does aren't entirely necessary. Like.. jumping in quicksand on purpose, for one. But, he showed you how to escape it.

I like the random stories he tells in every episode. They all mainly sound like this, "Around 2 years ago, an old person/couple got stranded in a mountain not very far from here. They ended up dying of hypothermia/heat exhaustion/shredded by bears." Hah, it's so great.
