10 April fools Prank Disasters Ranked
10 The End Of The World
In 1940, William Castellini, a press agent for Philadelphia’s Franklin Institute, caught a spark while listening to a Jack Benny broadcast that mentioned Orson Welles’s infamous “War of the Worlds” broadcast two years earlier. The show’s reference gave Castellini the idea to blend a serious lecture titled “How Will the World End?” with the date April 1, hoping to generate buzz.
He drafted a formal press release on March 31 proclaiming that astronomers at the Institute had confirmed the world would meet its demise at 3:00 PM EST on April 1. The release explicitly warned that this was no joke and even listed a phone number for further inquiries.
Local station KYW ran the release on the air, prompting a flood of frantic calls and letters from terrified residents. Many citizens, believing the warning to be genuine, expressed anger and fear once the truth emerged.
The station later claimed ignorance, shifting blame back to the Franklin Institute. Castellini was promptly dismissed from his post, and the episode remains a cautionary tale about the fine line between publicity and panic.
Whether KYW was genuinely duped or simply used Castellini as a scapegoat has never been settled, but the fallout was unmistakable: a career ruined and a public trust shaken.
9 The Aliens Invade Jafr
Even in the digital age, some people still fall for April 1 tricks, especially in regions where the tradition isn’t deeply rooted. In 2010, the Jordanian town of Jafr was duped by a sensational newspaper story alleging that three‑meter‑tall extraterrestrials had landed in the desert just outside the settlement.
Mayor Mohammed Mleihan reported that the alleged alien arrival caused widespread panic, with parents refusing to send children to school and even contemplating a full evacuation. Military troops were dispatched, only to find no trace of any spacecraft.
Once the hoax was uncovered, Mleihan threatened legal action against the Al Ghad newspaper. The paper issued an apology, insisting the piece was meant for entertainment, not terror. Speculation lingered about why Jafr was chosen, given its history of hosting both U.S. military forces and Al‑Qaeda elements.
8 Eruption Near Boston
Residents of the Greater Boston area know Great Blue Hill as a modest 15‑kilometre‑away hiking spot. On April 1, 1980, WNAC‑TV aired a fabricated bulletin claiming the hill had erupted, spewing ash and lava onto nearby homes.
Reporter Jan Harrison described a dramatic scene, linking the eruption to the recent activity at Mount St. Helens and suggesting a chain‑reaction geological event. The broadcast was spliced with stock footage of flowing lava and even featured fabricated statements from President Jimmy Carter and Governor Edward J. King, lending a veneer of authority.
Only at the segment’s end did Harrison hold up a card reading “April Fool.” By then, many viewers had already tuned out, but the damage was done: panic spread through the towns of Milton and Canton, with scores of residents calling emergency services and some beginning to evacuate.
The station faced severe repercussions. Executive producer Homer Cilley was terminated for failing to exercise sound news judgment, and the broadcast also violated FCC rules by presenting stock footage without proper attribution.
7 Google Drops The Mic
Google has built a reputation for elaborate April 1 jokes, rolling out dozens of temporary features each year. In 2016, however, the company misfired with its “Gmail Mic Drop”—a button that, when pressed, appended a minion‑style mic‑drop GIF to the email and automatically muted the entire thread.
The idea was meant to be a cheeky way to end conversations with flair. Unfortunately, many users accidentally hit the “Send + Mic Drop” button on serious business correspondence, not realizing the feature would silence replies.
Complaints surged as professionals discovered their inboxes frozen after sending a Mic Drop, with the minion GIF serving as an unintended final word. Google quickly pulled the feature within hours, acknowledging the unintended consequences.
6 Topless Stylist Causes Traffic Jam
Barber George Birko in Columbus, Ohio, thought a cheeky sign reading “Topless Stylist on Duty Today” would draw attention on April 1, 1980. Curious patrons flocked to his shop, only to find Birko busy cutting hair while wearing nothing but a tuxedo tie above his belt.
The spectacle attracted such a crowd that police were called to investigate a traffic jam forming outside the shop. Officers ordered the sign’s removal, and the Ohio Barber Licensing Board, tipped off by the vice squad, launched an inspection.
Inspectors found no actual “topless” stylists, deeming Birko’s shirtless state as non‑violative. Though the incident caused a brief legal hassle, Birko’s business doubled that day, proving the prank’s commercial success despite the chaos.
5 The New Voyage Of The Titanic
Beachy Head, a chalk headland on England’s southeast coast, is notorious for its dramatic cliffs and tragic history as a suicide hotspot. In 2001, a local radio DJ announced that a replica of the Titanic would sail past East Sussex, visible from the headland.
The ship was said to be built by a company called AFD—an acronym for April Fools’ Day—providing the only clue that the story was a gag. Thousands gathered, expecting to witness the historic vessel.
When the crowd realized they’d been duped, a massive 1.5‑metre crack opened in the cliff face due to the sheer number of people pressing against it. Authorities had to evacuate the area and cordon off the danger zone.
The radio station issued an apology, but the Maritime and Coastguard Agency expressed stern displeasure, noting the heightened risk of landslides and the foggy conditions that day.
4 Super Mario Bomb Scare
Super Mario, the iconic video‑game franchise, is instantly recognizable to gamers but not to everyone. In 2006, five teenage girls in Ravenna, Ohio, placed 17 gold‑wrapped boxes bearing a white question‑mark—reminiscent of Mario’s question blocks—outside key public buildings.
While gamers might have guessed the boxes contained power‑ups, the general public feared they were explosive devices. The local bomb squad was summoned, only to find the containers empty of any dangerous material.
The teenagers later confessed, explaining they had copied the design from an online art‑project site. Police chief Randall McCoy noted that, despite the scare, no other towns reported similar misunderstandings.
3 A Trip Around The World
Offering a free or heavily discounted deal is a classic prank trigger—people love a bargain and get angry when it’s a joke. In 1872, Thomas Cook organized the first escorted round‑the‑world tour. A century later, Times reporter John Carter announced that Thomas Cook would once again run a worldwide trip, this time at the 1872 price of 210 guineas (about $575).
He urged interested travelers to contact “Miss Avril Foley.” Hundreds queued at Thomas Cook branches, unaware the offer was a ruse, and flooded travel agents with angry inquiries.
The Times eventually admitted the hoax and apologized, but the backlash persisted. Carter was initially fired, though he was later reinstated after the controversy died down.
2 The Mouse In The Egg
In 1900, a practical‑joker fiancé in Binghamton, New York, decided to give his nervous bride‑to‑be, 19‑year‑old Edith Walrach, a terrifying surprise. He slipped a live mouse into her boiled egg, sealing the top with plaster of Paris before serving it for breakfast.
When Edith cracked the egg, the mouse darted out, causing her to scream, faint, and suffer three nervous fits throughout the day. A doctor had to intervene, and the incident left her in a critical condition.
The newspaper report never disclosed the couple’s eventual fate, but the prank’s severity was evident: a harmless breakfast turned into a medical emergency.
1 To Honor A Killer
In 1971, Texas Representative Tom Moore tried a risky April Fools’ stunt by drafting a resolution that would honor a Boston man for “unselfishly serving his country, his state, and his community.” The resolution cited the individual’s “noted activities and unconventional techniques involving population control and applied psychology.”
The resolution passed unanimously, only for everyone to realize it was meant to honor Albert DeSalvo—the notorious “Boston Strangler.” DeSalvo had confessed to 13 murders and was serving time for multiple rapes.
Moore withdrew the resolution amid widespread condemnation. Media outlets framed the episode as a lesson on legislative complacency, though the former lawmaker later clarified the prank was intended to expose how legislators often approve measures without reading them.
He had hoped the joke would be a harmless nudge, but the backlash was anything but.
