At one point Pepper (Woody Harrelson) tells Officer Sam "Mad Dog" Shaw (Ernie Hudson) that there are no real cowboys from Texas. However, later when asked about Bill Pickett, Woody didn't know who he was and replied ,"Oh, William!". Willie M. "Bill" Pickett is from Texas and was called the "Greatest Cowboy" of his day.
While at the police station Pepper is about to draw a mustache on a picture of the Lone Ranger. At the same time they are discussing the top of no black Cowboys. The legend of the Lone Ranger was based off US Marshal Bass Reeves the first black US Marshal.
