On 8 September 2004, Dan Rather reported on 60 Minutes that CBS had obtained documents revealing that President Bush had disobeyed orders while serving in the National Guard and had then used his family's influence to cover up his poor service record. The documents allegedly came from the files of Col. Killian, Bush's commanding officer in the Guard. Rather's news report generated controversy almost immediately. Bloggers pointed out that the documents in question looked as if they had been written in Microsoft Word, which would not have existed when Bush was serving in the Guard. Initially CBS paid no attention to the bloggers, but when it realized that its source for the documents, Bill Burkett, had lied about how he obtained them, it decided that it could no longer vouch for their authenticity. Rather apologized for airing the story.

On the evening of September 19, 1994 a stark warning was repeatedly broadcast to TV viewers in Taiyuan, a city in northern China. A message scrolled across an otherwise blank screen warning that the Sibuxiang beast, a mythical creature whose bite was said to be fatal, was not only real, but on the loose and heading towards the city. "It is said that the Sibuxiang is penetrating our area from Yanmenguan Pass and within days will enter thousands of homes," the message read. "Everyone close your windows and doors and be on alert."

The residents of Taiyuan panicked. Many of them barricaded themselves inside their homes, fearing to go out. Others called the local authorities to find out what was happening... More >>>

On 31 October 1992, Britain's BBC TV aired a 90-minute documentary called Ghostwatch. The program was advertised as a live investigation into reports of supernatural activity at a council house in North London. The show was anchored by a group of well-known television reporters: Michael Parkinson, Sarah Greene, Mike Smith and Craig Charles.

Michael Parkinson and Mike Smith both reported from a TV studio, where calls were being taken from the public. Experts on supernatural activity were interviewed via a satellite hook-up. Sarah Greene and Craig Charles reported live on location from the house itself.

However, events quickly took a sinister turn. A wet patch appeared in the middle of the carpet. The noise of cats was heard emanating from the walls, and scratches appeared all over body of a young girl... More >>>

Many child stars achieve success and stability as adults, but some child stars go from stardom to the opposite extreme of anonymity and failure, as if dragged down by the weight of their early fame. According to a segment that aired on ABC News's 20/20 in October 1990, this appeared to be the fate of the actor who had played Buckwheat in the 'Our Gang' comedies of the 1930s and '40s.

Buckwheat was the wide-eyed, African-American character played for almost ten years by William Thomas. He was famous for his signature phrase, "O-Tay!" After leaving the show, Thomas dropped from the public eye. 20/20 claimed that it had tracked him down to Tempe, Arizona where he was working at a low-paying job as a grocery bagger. It aired an interview with him in which he talked about the cruel twists and turns his life had taken.

Unfortunately for 20/20, the man they interviewed was not William Thomas. Thomas had worked as a film lab technician before dying in 1980 at the age of 49. The man 20/20 interviewed was an imposter named Bill English who had been claiming to be Buckwheat for the past 30 years. The week after it aired the segment, 20/20 admitted its mistake. In the ensuing scandal, a producer was fired and 20/20 was sued for negligence by the son of the real William Thomas.

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!)"

On January 21, 1985, the daily broadcast of the Donahue show was devoted to a typically unusual subject — gay senior citizens. But few people would later remember the topic of that day's show, because as the live broadcast progressed seven members of the audience proceeded to faint. Concerned by the bizarre outbreak of swooning, Donahue cancelled the rest of the show and sent everyone home.

The producers theorized that the hot temperature inside the studio might have caused the people to collapse, but a few days later Deborah Harmon, one of the fainters, admitted she had been paid to do so by the well-known prankster Alan Abel. He had also paid the six other audience members who had fainted.

Abel later explained that the stunt was designed as a protest against the deteriorating quality of daytime talk shows. He claimed that a group called FAINT (Fight Against Idiotic Neurotic TV) had spearheaded the protest. "We want to raise the consciousness of the public by going unconscious," he said.

The stunt attracted more censure than any of Abel's other pranks because critics charged that it could have inspired panic at a time when there was public concern over the possible spread of Legionnaire's disease.

G. Clifford Prout was a man with a mission, and that mission was to put clothes on all the millions of naked animals throughout the world. To realize his dream, Prout founded an organization, the Society for Indecency to Naked Animals (abbreviated as SINA). It was left unexplained why the society was 'for indecency' not 'against indecency'. More >>>

On April 1, 1957 the British news show Panorama broadcast a three-minute segment about a bumper spaghetti harvest in southern Switzerland. The success of the crop was attributed both to an unusually mild winter and to the "virtual disappearance of the spaghetti weevil." The audience heard Richard Dimbleby, the show's highly respected anchor, discussing the details of the spaghetti crop as they watched video footage of a Swiss family pulling pasta off spaghetti trees and placing it into baskets. The segment concluded with the assurance that, "For those who love this dish, there's nothing like real, home-grown spaghetti." The Swiss Spaghetti Harvest hoax generated an enormous response. Hundreds of people phoned the BBC wanting to know how they could grow their own spaghetti tree. To this query the BBC diplomatically replied, "Place a sprig of spaghetti in a tin of tomato sauce and hope for the best." To this day the Panorama broadcast remains one of the most famous and popular April Fool's Day hoaxes of all time. More >>>

During the 1950s Twenty One was one of the most popular quiz shows on TV. Its ratings soared when Charles Van Doren, son of Pulitzer Prize-winning poet Mark Van Doren, appeared as a contestant on the show in late 1956. Van Doren seemed unbeatable. For week after week he answered every question correctly, winning a total of $129,000. But in 1957 a previous contestant, Herbert Stempel, revealed that the entire show was rigged. Van Doren, it turned out, was being fed the correct answers. A congressional investigation followed, and NBC, the producer of the show, issued an embarrassed confession.
