origin of

I’ve always really liked the following joke:

*Once there were these two backpackers who see a bear begin to charge them so one backpacker takes off his hiking boots and puts on running shoes. His companion says, “you’ll never outrun the bear, why are you puting those on?” The guy with the running shoes repies, “I don’t have to outrun the bear, I just have to outrun you.” *

Does anyone know its origin?


Here’s another one though:

How do you tell brown bear crap from grizzly bear crap?

Brown bear crap had berry seeds and nuts in it, grizzly bear crap has bells and goose down in it.
