OPINION — This week’s subject is Things That Come Out Of Animals, which may sound disgusting and gross on the surface, but once you dig a little you’ll find that many things that come out of animals are disgusting and gross. Also useful. A good example is buffalo chips, which are not really chips at all. They also don’t come out of buffalo, not if you find them in the United States. Because buffalo aren’t native to the United States. Which is pedantic and annoying, I know, but there you go.
