I'm not a big enema queen, but the idea of sticking things up Man vs. Wild's Bear Grylls' ass IN ORDER TO SURVIVE definitely has its appeal. The gist of this clip is that sometimes, when the only water available is fetid or rancid, it's best to place it directly into your colon, so that you don't vomit and end up more dehydrated than before. Which makes sense. If I'm ever stranded on a raft with Bear Grylls, I will happily hydrate his colon, and let him hydrate mine. Then we'll probably be eaten by sharks, but there you go.
