The Origin of April Fool’s Day

Top 10 Worst April Fools Ever

Top 100 April Fool’s Day Hoaxes of All Time
As judged by notoriety, creativity, and number of people duped.

Note from the Curator: I created the first version of this list in the late 1990s. Back then, there was hardly any information collected about April Fool’s Day pranks, so I had to do a lot of research in newspaper archives to put this together. Luckily I was in grad school, so I had a lot of spare time on my hands ;-). Over the years I’ve tweaked the list, rearranging it slightly and adding new entries based on reader feedback and ongoing research, but my top choices have remained pretty much the same. This list is easily the most popular article I’ve ever posted on the Museum of Hoaxes. Extracts from it (some attributed, some not) can be found on hundreds of other websites. Plus, it’s inspired some spinoffs. A couple of years ago, someone created an iPhone app version of it (which I’ve never seen because I don’t have an iPhone), and the folks at the Drama Pod created a dramatized audio version of it in 2011. I hope you enjoy it — and if you know of any old hoaxes that I haven’t mentioned on the site, send me an email and let me know. ~Alex

On 1 April 1957, the respected BBC news show Panorama announced that thanks to a very mild winter and the virtual elimination of the dreaded spaghetti weevil, Swiss farmers were enjoying a bumper spaghetti crop. It accompanied this announcement with footage of Swiss peasants pulling strands of spaghetti down from trees. Huge numbers of viewers were taken in. Many called the BBC wanting to know how they could grow their own spaghetti tree. To this the BBC diplomatically replied, “place a sprig of spaghetti in a tin of tomato sauce and hope for the best.” More→

The April 1985 issue of Sports Illustrated contained a story about a new rookie pitcher who planned to play for the Mets. His name was Sidd Finch, and he could reportedly throw a baseball at 168 mph with pinpoint accuracy. This was 65 mph faster than the previous record. Surprisingly, Sidd Finch had never even played the game before. Instead, he had mastered the “art of the pitch” in a Tibetan monastery under the guidance of the “great poet-saint Lama Milaraspa.” Mets fans celebrated their teams’ amazing luck at having found such a gifted player, and they flooded Sports Illustrated with requests for more information. In reality this legendary player only existed in the imagination of the author of the article, George Plimpton, who left a clue in the sub-heading of the article: “He’s a pitcher, part yogi and part recluse. Impressively liberated from our opulent life-style, Sidd’s deciding about yoga —and his future in baseball.” The first letter of each of these words, taken together, spelled “H-a-p-p-y A-p-r-i-l F-o-o-l-s D-a-y — A-h F-i-b”. More→

In 1962 there was only one tv channel in Sweden, and it broadcast in black and white. But on 1 April 1962, the station’s technical expert, Kjell Stensson, appeared on the news to announce that, thanks to a new technology, viewers could convert their existing sets to display color reception. All they had to do was pull a nylon stocking over their tv screen. Stensson proceeded to demonstrate the process. Thousands of people were taken in. Regular color broadcasts only commenced in Sweden on April 1, 1970. More→

The Taco Bell Corporation took out a full-page ad that appeared in six major newspapers on 1 April 1996, announcing it had bought the Liberty Bell and was renaming it the Taco Liberty Bell. Hundreds of outraged citizens called the National Historic Park in Philadelphia where the bell was housed to express their anger. Their nerves were only calmed when Taco Bell revealed, a few hours later, that it was all a practical joke. The best line of the day came when White House press secretary Mike McCurry was asked about the sale. Thinking on his feet, he responded that the Lincoln Memorial had also been sold. It would now be known, he said, as the Ford Lincoln Mercury Memorial. More→

On 1 April 1977, the British newspaper The Guardian published a special seven-page supplement devoted to San Serriffe, a small republic said to consist of several semi-colon-shaped islands located in the Indian Ocean. A series of articles affectionately described the geography and culture of this obscure nation. Its two main islands were named Upper Caisse and Lower Caisse. Its capital was Bodoni, and its leader was General Pica. The Guardian‘s phones rang all day as readers sought more information about the idyllic holiday spot. Only a few noticed that everything about the island was named after printer’s terminology. The success of this hoax is widely credited with launching the enthusiasm for April Foolery that gripped the British tabloids in subsequent decades. More→

The 1 April 1992 broadcast of National Public Radio’s Talk of the Nation revealed that Richard Nixon, in a surprise move, was running for President again. His new campaign slogan was, “I didn’t do anything wrong, and I won’t do it again.” Accompanying this announcement were audio clips of Nixon delivering his candidacy speech. Listeners responded viscerally to the announcement, flooding the show with calls expressing shock and outrage. Only during the second half of the show did the host John Hockenberry reveal that the announcement was a practical joke. Nixon’s voice was impersonated by comedian Rich Little.

The April 1998 issue of the New Mexicans for Science and Reason newsletter contained an article claiming that the Alabama state legislature had voted to change the value of the mathematical constant pi from 3.14159 to the ‘Biblical value’ of 3.0. Soon the article made its way onto the internet, and then it rapidly spread around the world, forwarded by email. It only became apparent how far the article had spread when the Alabama legislature began receiving hundreds of calls from people protesting the legislation. The original article, which was intended as a parody of legislative attempts to circumscribe the teaching of evolution, was written by physicist Mark Boslough.

Burger King published a full page advertisement in the April 1st edition of USA Today announcing the introduction of a new item to their menu: a “Left-Handed Whopper” specially designed for the 32 million left-handed Americans. According to the advertisement, the new whopper included the same ingredients as the original Whopper (lettuce, tomato, hamburger patty, etc.), but all the condiments were rotated 180 degrees for the benefit of their left-handed customers. The following day Burger King issued a follow-up release revealing that although the Left-Handed Whopper was a hoax, thousands of customers had gone into restaurants to request the new sandwich. Simultaneously, according to the press release, “many others requested their own ‘right handed’ version.”

The April 1995 issue of Discover Magazine reported that the highly respected wildlife biologist Dr. Aprile Pazzo had found a new species in Antarctica: the hotheaded naked ice borer. These fascinating creatures had bony plates on their heads that, fed by numerous blood vessels, could become burning hot, allowing the animals to bore through ice at high speeds. They used this ability to hunt penguins, melting the ice beneath the penguins and causing them to sink downwards into the resulting slush where the hotheads consumed them. After much research, Dr. Pazzo theorized that the hotheads might have been responsible for the mysterious disappearance of noted Antarctic explorer Philippe Poisson in 1837. “To the ice borers, he would have looked like a penguin,” the article quoted her as saying.Discover received more mail in response to this article than they had received for any other article in their history.

During an interview on BBC Radio 2, on the morning of 1 April 1976, the British astronomer Patrick Moore announced that at 9:47 AM a once-in-a-lifetime astronomical event was going to occur that listeners could experience in their very own homes. The planet Pluto would pass behind Jupiter, temporarily causing a gravitational alignment that would counteract and lessen the Earth’s own gravity. Moore told his listeners that if they jumped in the air at the exact moment this planetary alignment occurred, they would experience a strange floating sensation. When 9:47 AM arrived, BBC2 began to receive hundreds of phone calls from listeners claiming to have felt the sensation. One woman even reported that she and her eleven friends had risen from their chairs and floated around the room. Moore’s announcement (which, of course, was a joke) was inspired by a pseudoscientific astronomical theory that had recently been promoted in a book called The Jupiter Effect, alleging that a rare alignment of the planets was going to cause massive earthquakes and the destruction of Los Angeles in 1982. More→
