Trivia

This is one of the only two episodes in which the guest star uses a pseudonym instead of their real name (the other being "Stark Raving Dad"). Following the legal troubles surrounding "Stark Raving Dad", the producers stated henceforce no pseudonyms would be allowed. As a result, all voice actors must use their true names in the credits of The Simpsons.
Dustin Hoffman's pseudonym 'Sam Etic' was chosen as reference to his character being Jewish or "Semitic".
In one particular scene, Maggie whimpers a little, Nancy Cartwright was asked to play Maggie and she accepted but she spotted her husband (they are divorced now) and her daughter (who was a baby at the time) walk in the studio. She asked one of the directors if her baby could do the little whimpers for Maggie. The director said yes and Nancy Cartwright's daughter actually made the whimpers of little Maggie.
Lisa makes reference to there not being many Jewish cowboys, to which Mr. Bergstrom says that there were a few. In actual history of the Old West, there was a multiracial makeup of cowboys and settlers, with there being cowboys of black, Mexican, and Indian heritage, as well as cowboys who were recent immigrants from places such as Russia, Germany, France.
