This is a bit of a rewrite of "Of Mice and Men" with the "Arnie" character as "Lenny," and Hoss as "George." The "Mongo" character from "Blazing Saddles" is also remarkably similar to Arnie. Alex Karas may very well have drawn from this for his role.
Arnie's fondness for baby pigs mirrors Lenny's penchant for rabbits, though he ironically points out that they are hairless as opposed to Lenny's furry rabbits.
Sheribelle the saloon girl toys with Arnie just as did Curley's wife in "Of Mice and Men" and she meets a similar fate.
Arnie's fate is also similar to Lenny's. Hoss catches up to Arnie as he runs from the posse and they have scene similar to Lenny and George's final scene, except that Hoss doesn't pull the trigger to save Arnie from the wrath of the posse. While George "takes" Lenny to his dream farm via his imagination just prior to his death, Hoss also literally takes Arnie to it post mortem.
