Over its long run, The Simpsons has often broken the fourth wall with success. Season 34, however, aimed at its own past and fell short. The gag itself was clever, yet the reference was incorrect, and nobody noticed it before the episode reached viewers.
The Joke That Should Have Worked
In “The Many Saints of Springfield,” episode 13 of season 34, Ned Flanders reminded Marge that he was once Bart’s substitute teacher. He said the mnemonic “CADF12” was all she needed to remember his brief time on the job. Later, when Bart collaborated with Skinner, Ned remembered that Marge’s son was still a hellion during his time teaching. The joke was transparently a reference to the relevant episode’s real-life production code.
Except the episode doesn’t exist.
No episode of The Simpsons bears the production code “CADF12.” There is, however, an outing with the code XABF12. That episode is “Left Behind,” season 29, episode 19, where Ned works as Bart’s teacher. The Simpsons swapped Bart and Lisa’s roles for the episode, and Ned’s memory of Bart’s grades and the days he missed was meant to reference that outing.
The trouble was with the code itself. The authors employed “CADF12” when they should have used the real “XABF12.”. It was merely a single letter switched around, yet that small change rendered the entire joke without meaning.
What Went Wrong
The creators of The Simpsons put the error there on purpose, according to Al Jean, who explained that the episode’s writer, who tweeted about it. Ned’s comments had to start with grade letters so they would make sense, and Bart himself could not get an “X” at school.
“Ned’s comment needed to begin with grade letters in order to make sense, and even Bart could not get an ‘X’ in school.”
Longtime viewers were meant to notice the joke as a quiet troll. A real-life production code that wasn’t quite accurate would be a simple way of baiting those who watch closely. The true purpose behind the gag, though, was more straightforward: the writers needed the line to open with grade letters, and Bart’s grades don’ had to carry an “X.”
Why The Simpsons Messed Up
Constantly breaking its own rules is what defines The Simpsons. Usually, that approach serves a surprising twist or a clever setup for a joke. This time, though, the show came close to referencing real life, but its fidelity to reality kept it from landing.
That The Simpsons points viewers toward the code, only for the code to turn out to be a nonsense string because of a changed letter, is rather amusing. The gag could have carried far more weight had Ned employed the correct XABF12 code instead. Doing so would not merely have made the Easter egg clearer, but would also have raised the question of just what Bart Simpson needed to do to earn an X grade.
The show survived earlier errors that nearly ended it, so this mistake will probably not lead to any serious consequences. It is a minor slip, born from a gag that failed to land.
The Long History Of Mistakes
Previous errors have occurred within The Simpsons, and not every one was intentional. The show’s continuity has always been very loose, and the series has acknowledged this directly through several jokes. Given its lengthy run, the timeline frequently adjusts to accommodate the passing years is hardly unexpected.
These errors are not the continuity changes that are simply unavoidable. Instead, they are real and unexplained mistakes that have little to no explanation at all. They are more noticeable in the early seasons, though the show still makes them from time to time.
Consider a case where it is not clear which class certain Springfield Elementary students really attend. A number of minor characters appear in both Bart and Lisa’s classes at different points, with no explanation ever given for why they move between the two.
Lisa shares her second-grade classroom with Ralph Wiggum, much to the dismay of their instructor, Miss Hoover. Yet on several occasions, Ralph appears in Bart’s class during earlier seasons. The evidence points to animators merely using an already known character to fill empty background space, without any deliberate planning behind it.
Sherri and Terri are also part of the group that fits this description. They are in fourth grade together with Bart. Yet in the season 13 episode “Little Girl in the Big Ten,” the twins appear on screen alongside Lisa during a gymnastics contest. The reason behind their inclusion in a second grade setting is never addressed. There is no explanation offered for this inconsistency beyond the possibility that the writers simply failed to remember a previously established detail about the show.
One more instance of a notable error concerns Bart’s murderous nemesis, Sideshow Bob. Sideshow Bob was introduced in The Simpsons season 1, and found himself in jail by the end of his debut appearance. It wasn’, which is resolved in the season 3 episode “Black Widower”, when Bob comes out from behind bars.
However, he can also be seen singing carols with a group of Springfield residents in season 2’s “Bart Gets An F.” Just like Ralph occasionally showing up in Bart’s class, this is a clear example of animators on The Simpsons making an avoidable error and using an established character to fill in background space.
The Show’s Legacy
Matt Groening created The Simpsons, and its first episode appeared on television on December 17, 1989. Over the years, the series has become known for its writers’ habit of making jokes about themselves, including the usual patterns found in family sitcoms and the rules of TV production.
There is much to praise about the show’s willingness to experiment, yet not every attempt at humor lands. Some of the jokes were clever, while others failed to connect. The gap between success and failure usually comes down to how carefully each idea has been crafted.
For years, The Simpsons has been known for continuity errors, and the show has turned some of these into jokes. To keep up with the years that have passed, the timeline keeps changing. One example is the story of Marge and Homer’s first meeting, which has been moved to later decades on more than one occasion.
When the writers of the show call out their own errors, the ones that slip by unnoticed tend to be even more obvious. A deliberate mistake from season 34 was meant to be clever, yet it went wrong. Still, it remains a funny one. What made it work was the show’s own drawing of attention to the code, which became meaningless because of a changed letter.
