That guy on the Discovery channel show, "Man against the Wild" or something like that (premise is: he's an ex British Special Forces dude and gets dropped into the wilderness somewhere and has to survive on his own with no food or water for several days and make it to the pick-up point miles away), he'll eat anything. I've seen him eat spiders, scorpions (stinger removed of course). It's gross, I'd rather die I think.
