first time i read about the surinam toad, and how they give birth, i got a serious case of the heeby-jeebies. try a google search if you have a strong stomach. :o
and to top it off, i heard about a cheese called casu marzu. look it up, there are maggots in the middle, and they are supposed to be there, and are even eaten. and get this, if the maggots are dead, THAT is when the cheese has gone bad!
