Maybe you'll find inspiration to play a prank on someone tomorrow.
#1: The Swiss Spaghetti Harvest1957: 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."
#2: Instant Color TV1962: In 1962 there was only one tv channel in Sweden, and it broadcast in black and white. 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.
#3: The Taco Liberty Bell1996: The Taco Bell Corporation announced 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.
#4: The Left-Handed Whopper
1998: Burger King published a full page advertisement in 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."
#5: UFO Lands in London1989: On March 31, 1989 thousands of motorists driving on the highway outside London looked up in the air to see a glowing flying saucer descending on their city. Many of them pulled to the side of the road to watch the bizarre craft float through the air. The saucer finally landed in a field on the outskirts of London where local residents immediately called the police to warn them of an alien invasion. Soon the police arrived on the scene, and one brave officer approached the craft with his truncheon extended before him. When a door in the craft popped open, and a small, silver-suited figure emerged, the policeman ran in the opposite direction. The saucer turned out to be a hot-air balloon that had been specially built to look like a UFO by Richard Branson, the 36-year-old chairman of Virgin Records. The stunt combined his passion for ballooning with his love of pranks. His plan was to land the craft in London's Hyde Park on April 1. Unfortunately, the wind blew him off course, and he was forced to land a day early in the wrong location.
#6: Flying Penguins
2008: The BBC announced that camera crews filming near the Antarctic for its natural history series Miracles of Evolution had captured footage of Adélie penguins taking to the air. It even offered a video clip of these flying penguins, which became one of the most viewed videos on the internet. Presenter Terry Jones explained that, instead of huddling together to endure the Antarctic winter, these penguins took to the air and flew thousands of miles to the rainforests of South America where they "spend the winter basking in the tropical sun." A follow-up video explained how the BBC created the special effects of the flying penguins.
#7: The Skyforest Orange-Bearing Pine Trees1950: Motorists driving along the scenic Rim of the World highway near Lake Arrowhead in Southern California discovered that the pine and cedar trees lining the road had all grown oranges overnight. The transformation was the work of the residents of the nearby town of Skyforest, led by the cartoonist Frank Adams. They had crept out during the night and strung 50,000 oranges in the trees along a one-mile section of the highway. The fruit was left over from the recent National Orange Show in San Bernardino.
#8: Drunk Driving on the Internet
1994: An article by John Dvorak in PC Computing magazine described a bill going through Congress that would make it illegal to use the internet while drunk, or to discuss sexual matters over a public network. The bill was supposedly numbered 040194 (i.e. 04/01/94), and the contact person was listed as Lirpa Sloof (April Fools backwards). The article said that the FBI was going to use the bill to tap the phone line of anyone who "uses or abuses alcohol" while accessing the internet. Passage of the bill was felt to be certain because "Who wants to come out and support drunkenness and computer sex?" The article offered this explanation for the origin of the bill: "The moniker 'Information Highway' itself seems to be responsible for SB 040194... I know how silly this sounds, but Congress apparently thinks being drunk on a highway is bad no matter what kind of highway it is." The article generated so many outraged phone calls to Congress that Senator Edward Kennedy's office had to release an official denial of the rumor that he was a sponsor of the bill.
#9: The Great Comic Strip Switcheroonie
1997: Comic strip fans opened their papers on April 1, 1997 and discovered their favorite strips looked different. Not only that, but in many cases characters from other strips popped up out of place. The reason for the chaos was the Great Comics Switcheroonie. Forty-six comic-strip artists conspired to pen each other's strips for the day. For instance, Scott Adams of Dilbert took over Family Circus by Bil Keane, where he added a touch of corporate cynicism to the family-themed strip by having the mother tell her kid to "work cuter, not harder." Jim Davis of Garfield took over Blondie, which allowed him to show his famous overweight cat eating one of Dagwood's sandwiches. The stunt was masterminded by Rick Kirkman and Jerry Scott, creators of the Baby Blues comic strip. When asked why he participated, Scott Adams noted, "You don't get that many chances to tunnel under the fence."
#10: Viagra for HamstersIn 2000 The Independent reported that Florida researchers had developed a Viagra-like pill to treat sexually frustrated pets, including hamsters. Veterinarians were said to have greeted the news with derision, but the article pointed out that there are few things as sad as a pet suffering from feelings of sexual inadequacy, noting that "It's not unknown for a guinea pig to sit in its cage thinking, 'I haven't had sex for months. Am I so unattractive?'." Owners were instructed to simply grind the pills up and sprinkle them in the pet's food. Laying some newspaper down on the floor once the pills began to take effect was also advised. The pills were to be marketed under the brand name Feralmone.
