the ol' expression about hot dogs is that they are made from lips and corn shoots (had to change the word).
i think if you're gonna kill an animal to eat, you should use as much of it as possible. try to waste nothing. one of my fav side dishes for brekkie when i'm in south jersey, "down the shore", or near philadelphia is something called scrapple. literally made from the scraps left over from an animal, hence the name. commercial scrapple is crap, but i've had homemade, with barley and oats added and it was deelish.
