Consider the recent Comanche Moon. The main Indian character was named Buffalo Hump after a Comanche who really existed. Some aspects of Buffalo Hump's life were incorporated into the series as well.
But "Buffalo Hump" is a rather prosaic and unimaginative name. If the only goal of the series was to entertain, why not give the main Indian a more entertaining name? Why not give him a name that would have kids shrieking and adults chuckling every time they heard it?
Some possible names:
Some of these names are real knee-slappers. They're certainly more entertaining than boring ol' "Buffalo Hump." So why not use one of these names to maximize the show's entertainment value? What's the justification for using a historically accurate name if the series' only goal is to entertain?
If anyone can offer a satisfactory answer to this question, I'll give him or her a cookie. So take your best shot. Explain to me why McMurtry used the bland "Buffalo Hump" in a piece of pure entertainment.
