In January 2008 five Iranian speedboats approached three U.S. Warships in the Persian Gulf. The U.S. warships attempted to contact the Iranians: "This is coalition warship. I am engaged in transit passage in accordance with international law. I maintain no harm. Over!" A radio operator on one of the U.S. warships then heard a voice reply, "I am coming to you... You will explode in... minutes." At first the U.S. warships believed this message to be coming from the Iranian speedboats. However, it has since been argued that the mysterious threatening message probably came from a "Filipino Monkey" prankster. More >>>

The Donside Paper Company had for years sponsored an annual contest for graphic design students. In 2000, to spice things up a bit, the company decided to give its contest a slightly different spin. Entrants were challenged to respond to one of three briefs: 1) to promote the Bermuda Triangle as a holiday destination; 2) to design a welcome pack for a shopaholics' association; or 3) to tell a lie convincingly.

The competition seemed to be going well, and many entries had already been received, when the participating colleges received a letter on Donside stationery explaining that the contest had regrettably been cancelled. Obediently, the schools began to turn away new entries. In a panic, Donside called to ask what they were doing, and only then did the schools realize their mistake. The cancellation letter had itself been an entry from a contestant who had taken the challenge to "tell a lie convincingly" to heart. Hundreds of letters and phone calls were required to rectify the situation. However, the colleges took it all in stride. One of them commented, "Isn't it funny — it's the ultimate lie." More >>>

A press release distributed to the media in Columbus, Ohio announced the formation of a new charity that would benefit the homeless by providing them with guns and ammunition. It was called the "Arm the Homeless Coalition." News of this charity was soon picked up by the national media and generated enormous controversy. But when an Ohio reporter tried to track down the Director of the Arm the Homeless Coalition, his investigation led him instead to a group of Ohio State University students who admitted the entire thing was a joke.

In July 1990 Carina Guillot and her 12-year-old daughter, Jocelyn, were visiting relatives in Florida when they wandered into a Toys 'R' Us store and spotted something very unusual. Standing inside a sealed cardboard package among the ranks of Ken dolls dressed in their standard-issue outfits was a Ken decked out in a purple tank top and sporting a lace apron on top of a polka-dotted skirt. Mrs. Guillot immediately thought, "Oh my God, now we have a crossed-dressed Ken." More >>>

On 27 April 1986, late night HBO subscribers watching the movie "The Falcon and the Snowman" were surprised by a sudden interruption of service. A color bar test pattern appeared on the screen for 4 ½ minutes. It was accompanied by a text message: "Good Evening HBO from Captain Midnight. $12.95/month? No Way! (Showtime/Movie Channel Beware!)"

Caltech is known for producing world-class scientists and engineers. But a few of its students have also demonstrated a flair for the law, as a highly controversial 1975 prank that turned on the legalistic reading of a sweepstakes entry form proved.

The sweepstakes in question was held by McDonald's. It ran from March 3rd to March 23rd, 1975, at 187 participating McDonald's restaurants in Southern California. The prizes included a year of groceries, a Datsun Z, McDonald's gift certificates, and cash. But one part of the contest rules caught the attention of three Caltech students who lived in Page House — Steve Klein, Dave Novikoff, and Barry Megdal. The part they noticed was the phrase "Enter as often as you wish." What if, the Caltech students wondered, a person entered the sweepstakes one million times? More >>>

In 1963 an entrepreneur conceived of a way to promote antisocial tendencies and profit from it. Charlie Hollis, a 37-year-old copywriter and Brooklyn College sophomore, printed up stickers that bore messages such as LOATHE THY NEIGHBOR and KICK A PUPPY TODAY. He then placed an ad for his misanthropic product in the Village Voice: More >>>

In early 1958 Michigan motorists began to report sightings of a "little blue man". The glowing figure, who looked like a spaceman from a science-fiction movie, would appear out of nowhere on rural roads, and then just as suddenly disappear. When startled motorists stopped to investigate, they could find no trace of him.

As time progressed, the sightings grew more fantastic. Some said the man appeared to be ten-feet high. Others thought he was only two-feet high. One motorist claimed he "ran faster than any human."

The police began to search for what, or who, was causing these sightings. Their search ended when three young men — Jerry Sprague, Don Weiss, and LeRoy Schultz — came forward and confessed. The young men explained how all the reports of flying saucers in the news had given them an idea for a prank. They created a costume consisting of long underwear, gloves, combat boots, a sheet with holes cut out for the eyes, and a football helmet to which they attached blinking lights. They then spray-painted the costume glow-in-the-dark blue (inspired by a song popular on the radio at the time, "Little Blue Man" by Betty Johnson). Sprague wore the costume, noting that "it was my underwear and I was the only one it would fit."

The trio staked out rural roads at night. Sprague would hide in a ditch, and when a motorist approached, he would leap out and run along the road to attract their attention before making a quick getaway by jumping into the trunk of the car driven by Weiss and Schultz. They did this on at least eight or ten nights, over a period of weeks.

The police let the pranksters off with a warning not to do it again.

In 1956 runners bore the Olympic flame across Australia, on a path from Cairns to Melbourne, where the summer games were to be held. But before the flame even got as far as Sydney, it had to endure a series of setbacks. Torrential rains soaked it. Burning heat almost overwhelmed the runners. The flame even went out a few times. Then in Sydney itself it encountered a situation unique in Olympic history.

Cross-country champion Harry Dillon was scheduled to bear the flame into Sydney, where he would present it to the mayor, Pat Hills. After making a short speech, Hills would pass the flame along to another runner, Bert Button.

Thirty-thousand people lined the streets of Sydney waiting for Dillon to arrive. Reporters stood ready with their cameras to record the historic occasion. Finally the runner appeared, bearing the flame aloft, and everyone began cheering. As the crowd pressed forward a police escort surrounded the runner in order to keep order.

With this escort around him, the runner made his way through the streets all the way to the Sydney Town Hall. He bounded up the steps and handed the torch to the waiting mayor who graciously accepted it and turned to begin his prepared speech.

Then someone whispered in the mayor's ear, "That's not the torch." Suddenly the mayor realized what he was holding. Held proudly in his hand was not the majestic Olympic flame. Instead he was gripping a wooden chair leg topped by a plum pudding can inside of which a pair of kerosene-soaked underwear was burning with a greasy flame. The mayor looked around for the runner, but the man had already disappeared, melting away into the surrounding crowd. More >>>

July 11, 1947: Ten days after residents of Twin Falls, Idaho reported seeing flying saucers in the sky, a woman reported finding a flying saucer embedded in the lawn of her neighbor's home. Police came out to investigate, followed by the FBI and three army officers who flew out from Fort Douglas, Utah. What they found was a small, gold-and-silver-colored saucer about the size of a bicycle wheel. It had gouged long strips in the lawn as it landed. The army officers removed the saucer and took it to Salt Lake City for closer investigation. But the police, working on a tip, then identified the saucer as the creation of four teenage boys, who had spent several days building it out of radio tubes, wires, an old phonograph, and discarded electrical parts. The boys claimed it was "all a joke." Because of their age, no charges were brought against them.

Jim Moran (1907-1999) was called, at various times, "super salesman number one," "America's No. 1 prankster," and "the last great bunco artist in the profession of publicity." He became famous during the 1930s and 40s for devising outrageous stunts on behalf of his clients. His favorite technique was to test the validity of popular sayings. For instance, he sold an icebox to an eskimo, found a needle in a haystack, and walked a bull through a china shop. More >>>

The illustrator Hugh Troy was frustrated by the crowds at New York's Van Gogh exhibit, which made it hard for art lovers such as himself to view the works. He was also convinced that most of the people were there out of lurid interest in the man who had cut off his ear, not out of a true appreciation for the art. To prove his point, he fashioned a fake ear out of a piece of dried beef and mounted it in a velvet-lined shadow box. He snuck this into the museum and stood it on a table in the Van Gogh exhibit. Beside the box he placed a sign: "This is the ear which Vincent Van Gogh cut off and sent to his mistress, a French prostitute, Dec. 24, 1888." More >>>

In 1930 Republican leaders throughout the United States received letters inviting them to a May 26 party at Cornell University in honor of the sesquicentennial birthday anniversary of Hugo Norris Frye, aka Hugo N. Frye. The letter explained that Hugo N. Frye had been one of the first organizers of the Republican party in New York State. None of the politicians could make it to the event, but almost all of them replied, expressing sincere admiration for Frye and their regret at not being able to attend.

Unfortunately for the Republican leaders who responded, Hugo N. Frye did not exist. He was the satirical creation of two student editors at the Cornell Sun. Hugo N. Frye was shorthand for "You go and fry!" More >>>

By trade Hugh Troy (1906-1964) was an artist. He illustrated many children's books, including "Maude for a Day," "The Chippendale Dam," and "Five Golden Wrens." But by nature he was a practical joker, with numerous pranks to his credit. When asked once what advice he would give to aspiring practical jokers, he replied that one should never sit down and try to deliberately think up a practical joke. This was a sure way to arrive at uninspired ideas. Instead, a prankster needs to seize the moment, grabbing opportunities as they arise. More >>>

After a heavy snowfall, the footprints of a large animal were found on the campus of Cornell University, leading up to the shore of the frozen Beebe Lake. A hole in the ice indicated that the animal must have fallen in and drowned.

A zoologist examined the tracks and identified them as those of a rhinoceros. Word of the rogue rhinoceros spread around town, and since the University got its water supply from the lake, many students declared they were no longer going to drink the water. Many of those who did drink it, swore they could taste rhinoceros.

The tracks turned out to be the work of Cornell student Hugh Troy. He and a friend had borrowed a rhino-foot wastepaper basket from a professor's house. They had weighted it down with scrap metal then attached it to a clothesline. Holding the clothesline at either end, they made their way across campus, creating a trail of tracks in the snow up to the edge of the lake.

The rhinoceros footprints are one of the most famous pranks in Cornell's history. However, there is no documentation to prove that the prank happened. Therefore, some suggest it may only be a legend.
