There was a “Far Side” cartoon where an American Indian was holding up an odd-shaped bone or piece of cartilage and saying to another Indian: “We don’t know what this is, but it’s the only part of the buffalo we don’t use.”
I find it ironic that the same people who hold up the American Indians as good, because “they used every bit of the buffalo” excoriate modern slaughter houses because they use every bit of the cow.
Indians only used every bit of a buffalo when it was convenient.
