Writing with the Masters. Study Chapters 6 and 9 for humor. In Chapter 6, both Native Americans have the word "Satan" for the root word of their names, Satanta and Satank. In Chapter 9, Larry McMurtry turns humor on and off like a switch, starting with a massacre had already happened or was about to happen. McMurtry calls this slim new work a ballad; you may want to look up the term.
