|The Telltale Head||
- The episode title is a reference to the short story "The Tell-Tale Heart" by Edgar Allan Poe. In addition, Bart actually hears the head talking when he is overcome with guilt, similar to Poe's character's hearing the still-beating heart of the man he murdered in the story.
- The Bridge over the River Kwai - the line "What have I done?", as quoted by Bart just after he cut the head off the statue.
- When Bart awakes to a find the head of Jebediah Springfield in bed next to him, it is reminiscent of the scene from "The Godfather" where Tom Hagen (Robert Duvall) "persuades" Woltz to cast Fontane in the movie by leaving the head of the producer's prize racehorse in his bed.
- When Bart skateboards in the streets, he shouts "Cowabunga!", the battle cry of the Teenage Mutant Ninja Turtles.

- The football announcer on Homer's car radio says, "This could be the most remarkable comeback since Lazarus rose from the dead."
- Announcer: "Wolodarsky takes it at the 5... oh my, he fumbles," reference to show writer-producer Wallace Wolodarsky.

- Kearney stands on the lawn and leans on a sign that reads "Keep off the Grass."
- Sideshow Bob's hair started as an afro in the middle of the episode, but in the final scene, he has his trademark spiky hair.
- When Bart asks Dolph, Kearney and Jimbo how they got the stolen merchandise from the Kwik-E-Mart, Jimbo replies, "Five finger discount, man," even though characters in The Simpsons only have four fingers.
- First full appearance of Krusty the Clown on 'The Simpsons'.
- First appearances of Reverend Lovejoy, Apu, Ms. Albright, Sideshow Bob, Dolph, Kearney, and Jimbo Jones.
- First appearance of the First Church of Springfield, Bart and Lisa's Sunday school, the Kwik-E-Mart and the Aztec Theater.
- This is the first time Smithers is shown with light gray hair and a green jacket.
- This is the first time Chief Wiggum is shown with brown skin and black hair, although he made his debut appearance in "Homer's Odyssey" with his blue hair and yellow skin.
- According to the producers, this episode marked the first hint towards Smithers' sexuality (When Mr. Burns mentioned that he loved Smithers, Smithers replies that "the feeling is more than mutual, sir.")
- When Barney asks how long Bart's story will take Bart says, "23 minutes and 5 seconds," meaning the length of the episode.
- In this episode, Dolph and Jimbo originally had each other's voice before they were later switched.
- When the bullies and Bart were watching the clouds, Kearney noted a guy being cut in the back by a switchblade; that guy resembled Hans Moleman.
- Several reruns of this episode, as well as the American DVD release of The Complete First Season cut out part of Bart's speech to the mob, in which he points out that removing the head made everyone realize that they were "taking the town's heritage for granted". This specific part of the speech did not exist in the original reel of the episode that was delivered to the Fox Network, and was the editorial creation of the network censors in compliance of the FCC's 1989 ruling that every serial animated television show transmitted include at least 28 seconds of educational content. However, this version of the ending is preserved on international editions of the DVD, such as Spain and Germany.
- It is not explained how the citizens of Springfield came across the knowledge needed to arrange themselves into a mob to confront Homer and Bart with the head (though it is possible that Homer contacted the authorities beforehand).
- Starting in Season 20, Jebidiah's head is sawed off in the intro.
- This is the first episode to feature Tress MacNeille in the voice cast, voicing Dolph and Ms. Albright. She would later go on to appear in every episode, more than any of the "Also Starring" cast members, starting with Season 11.
- The questions which Ms. Albright is asked, such as "do cavemen go to Heaven?" are all taken verbatim from a 1985 Life in Hell comic strip entitled "Kids' Questions About Death."

- Dolph would not be named until "Kamp Krusty".
- This episode implies that the Presbylutheran Church bans gambling. This is inconsistent with later episodes.
- When Bart is asking Ms. Albright questions, the upper portion of his face moves to the opposite side of his mouth.
- Ms. Albright's teachings are incorrect; the Bible explicitly states that humans and animals coexist in Heaven. Her lines in later episodes suggest that she may have misread parts of the Bible.
- When Bart enters the Kwik-E-Mart, the doors need to be pushed open to get through. When Bart leaves, the door slides open.
- The man with the moustache watching Space Mutants 4 is first seen with yellow skin but it turns brown when Bart blows a raspberry.
- When Bart returns home when Lisa is watching Krusty, the door is seen opening on its own for a split-second.
