The part about dumpster diving reminded me of when I used to help a friend of mine slop his pigs. He had arrangements with a few restaurants and old folks homes for their leftover food and we would drive around, pick it up in these large plastic garbage bins and feed it to his pigs. It would always surprise me when he would often pick over the food before we gave it to the pigs, looking for things like chicken legs which he would summarily devour. I never could bring myself to do it.
