I'm having some very wierd visuals with this. Like for example, that at least some of these are the world's deceased, and this is their way of giving back to the community. "Man, Fred's much tastier than I figured he would be. You could tell that it wasn't his chloresterol that took him out." =p
Also a scene from the Hitchhiker's Guide to the Galaxy comes to mind, where Arthur and the gang are at the Restaurant at the End of the Universe. The main course comes out, introduces himself to the party, and explains that what could be more humane than an animal that was bred to *want* to be eaten.
