All twelve of these pass the test: the episode exists, the date fits, the real event definitely came afterwards. What changes radically from one case to another is the merit. Some are genuine strokes of statistical luck, others reasonable bets on a news story already well under way, and one or two are outright parodies of past events turned the wrong way round.
Bengt Holmström's Nobel
26 SEPTEMBER 2010 → OCTOBER 2016
In "Elementary School Musical" (season 22, episode 1, broadcast on 26 September 2010), the Springfield pupils bet on the future Nobel laureates. Milhouse backs the MIT economist Bengt Holmström; in the episode, another name wins. In October 2016, Holmström genuinely received the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, alongside Oliver Hart.
Olympic curling
14 FEBRUARY 2010 → FEBRUARY 2018
"Boy Meets Curl" (season 21, episode 12, broadcast on 14 February 2010) sends Homer and Marge to the Olympic Games in mixed doubles curling. They take gold against Sweden, thanks to a Marge who did not know she was left-handed. Eight years later, in Pyeongchang, the men's team from the United States beat Sweden in the final and won the first ever American Olympic title in the discipline.
The fall of FIFA
30 MARCH 2014 → 27 MAY 2015
In "You Don't Have to Live Like a Referee" (season 25, episode 16), the executive vice-president of an international football federation comes looking for Homer because he finally needs an honest referee, rot having spread everywhere — then gets arrested mid-conversation. Fourteen months later, Swiss police detained FIFA officials in Zurich, at the request of the American justice system.
Germany world champions
MARCH 2014 → JULY 2014
The same episode has Germany beat Brazil in the World Cup final. In reality, Germany was indeed crowned in July 2014 — but by beating Argentina in the final, after crushing Brazil 7-1 in the semi-final. Two good teams, the wrong bracket: the coincidence is real, the prediction only partial. The shares, of course, never keep the caveat.
Tomacco
7 NOVEMBER 1999 → 2003
In "E-I-E-I-(Annoyed Grunt)" (season 11, episode 5, broadcast on 7 November 1999), Homer fertilises his field with plutonium and harvests tomacco, an inedible and addictive cross between tomato and tobacco. In 2003, Rob Baur, a fan from Oregon, grafted a tomato plant onto tobacco roots. The plant grew, bore fruit, and its leaves did indeed contain nicotine.
Gunter and Ernst
16 DECEMBER 1993 → 3 OCTOBER 2003
The episode "$pringfield" (season 5, episode 10) stages two glittering German illusionists, a transparent parody of Siegfried and Roy, attacked mid-act by their white tiger Anastasia. Almost ten years later, on 3 October 2003, Roy Horn was seriously injured on stage in Las Vegas by one of the white tigers from his own show, which ended the duo's career.
Lady Gaga suspended above the crowd
20 MAY 2012 → 5 FEBRUARY 2017
In "Lisa Goes Gaga" (season 23, episode 22), the singer flies over Springfield hooked to cables, in a sparkling outfit and thigh-high boots. At the Super Bowl in February 2017, she comes down from the roof of the Houston stadium in a very similar staging. Except that the show was parodying aerial numbers Gaga was already performing in concert. More on the show's guest stars.
The rigged voting machine
2 NOVEMBER 2008
The opening of "Treehouse of Horror XIX" (season 20, episode 4) shows Homer trying to vote for Barack Obama on an electronic machine that stubbornly records votes for John McCain, before killing him and spitting out his body. Al Jean presented the gag as a comment on irregularities many already suspected. To be cross-referenced with the Treehouse of Horror episodes.
Lisa's video call
MARCH 1995 → LATE 2000s
The same episode as the communicator watch shows Lisa announcing her engagement to Marge by videophone, in 2010. Consumer video calling would indeed take hold around then, with Skype and later FaceTime. As with the watch, the idea had been circulating in science fiction for decades, and videophones existed in industrial demonstrations long before the episode.
The post-election blackboard
13 NOVEMBER 2016
Five days after the American election, the episode "Havana Wild Weekend" opens on a one-sentence blackboard gag: "BEING RIGHT SUCKS". It is the best answer the production has ever given to its own legend. Our article on Bart's blackboard looks back at the most memorable punishments.
The Osaka flu
6 MAY 1993
"Marge in Chains" (season 4, episode 21) tells of an epidemic from Japan, spread by a sick worker who sneezes into a shipment of juicers. The panic, the miracle cures and the angry crowd are all there. It is a genuine epidemic satire — but the episode comes after a long series of real pandemics, and it obviously names no future virus.
The Super Bowl tip
23 JANUARY 1992
"Lisa the Greek" (season 3, episode 14) makes Lisa an unbeatable tipster, and the original broadcast, three days before Super Bowl XXVI, does give the future winner — who went in as the overwhelming favourite. The rest of Lisa's prophetic record comes from the annual reruns redubbed by Fox to match that day's line-up.
How a false prediction is made
Eight techniques, from the brushstroke to the generated image, recognisable at a glance.
Fakes do not come from nowhere: they follow a handful of recipes, and once you know them you spot them in three seconds. The show's visual style is a gift to forgers — flat colours, simple outlines, yellow characters recognisable among thousands — and at the same time a curse, because the slightest departure from the model leaps out at a fan.
Local retouching
The historic technique: you start from a real shot and add the shock element. Flames on a cathedral, a character in the foreground, a building collapsing. The background, the colours and the framing stay authentic, which makes the screenshot immediately credible. The counter is a single manoeuvre: find the original screenshot from the same episode and compare.
Substituted text
The Simpsons loves signs and television news banners: the forger's dream playground. Replacing "Apocalypse Meow" with "Corona Virus" takes ten minutes' work, and that is exactly the trick behind the biggest fake of 2020. Our profiles of Kent Brockman show just how much of an institution those banners are.
The montage of shots
For video fakes, clips from different episodes are stuck end to end, without transitions, with unsettling music and a voice-over. Each clip is authentic, the sequence is not. That is the recipe behind the fake about the Los Angeles fires. An unbeatable clue: the drawing style changes from one second to the next, because the seasons are far apart.
The generated image
For a few years now, many new fakes have no longer been retouches: they are entirely generated images that exist in no episode. They fail the reverse image search, and they betray the model on the details: extra hairs on Homer, surplus fingers, illegible text, inconsistent shadows, settings that match no known location.
Reversed chronology
No graphic trickery here: you take recent content mocking a past event and present it as predating it. That is exactly the case of the Trump Tower escalator and the Riyadh orb. It is technically the most honest technique and intellectually the most dishonest — and fortunately the simplest to dismantle, since a single date is enough.
Recycled fan art
Thousands of amateur artists depict the news in the show's style. These images are published as tributes, with no intention whatsoever to deceive — then an account picks them up a few months later and presents them as episode screenshots. The drawing about George Floyd followed exactly that path, much to its author's dismay.
The aggregator account
Accounts entirely devoted to alleged predictions post several times a day, without ever citing a single source. Their business model is engagement, not accuracy, and they quietly republish the same fakes every six months. An account that never gives an episode number never checks anything: it is as simple as that.
The undatable prophecy
The last technique is the laziest: announce that the show foresaw a vague event for some year to come. With no episode, no shot, no date, there is strictly nothing to refute. That is why those lists come back every January: they cost nothing to write and bring in clicks for twelve whole months.
