First appearances of: Apu, Krusty the Clown, Sideshow Bob, Jimbo, Dolph, Kearney, Reverend Lovejoy and Ms. Albright, the Sunday School teacher.
The look of Sideshow Bob hasn't been established yet, as he has an afro hairstyle, rounder nose, a pudgy body, a different Sideshow necklace and an armband.
The layout and the colors of Moe's Tavern, aren't quite established yet in this episode. The interior is all red, and the entrance door seems to lead to another room and not outside.
The TV version of this episode has an extra scene where Bart explains to the townspeople that they've lost their way as Springfieldianites by being so quick to lynch a ten-year-old boy who actually feels sorry for what he's done. The DVD version doesn't have this scene (nor does the FXX rerun of this episode as seen on the "Every Simpsons Ever" marathon). The TV-exclusive scene was shoehorned because FOX wanted the episode to have a moral about people losing their town pride. It is included in the Disney+ version.
Bart's blackboard joke for this episode is "I Did Not See Elvis." However, one of the lines reads, "I Did See Elvis."
