April fool's day

Above: April Fool's Day Joke gone bad. (Cartoon credit) Yes, I know it's tomorrow, April 1st. But, in some parts of the world, it's already April 1st, so there!

I ran into this interesting article on Yahoo news of the top pranks pulled off on April Fool's Day. I haven't heard of all of these, but here are the interesting ones (to me):

-- Sweden in 1962 had only one television channel, which broadcast in black and white. The station's technical expert appeared on the news to announce that thanks to a newly developed technology, viewers could convert their existing sets to receive color pictures by pulling a nylon stocking over the screen. In fact, they had to wait until 1970.

- In 1996, American fast-food chain Taco Bell announced that it had bought Philadelphia's Liberty Bell, a historic symbol of American independence, from the federal government and was renaming it the Taco Liberty Bell.

Outraged citizens called to express their anger before Taco Bell revealed the hoax. Then-White House press secretary Mike McCurry was asked about the sale and said the Lincoln Memorial in Washington had also been sold and was to be renamed the Ford Lincoln Mercury Memorial after the automotive giant.

-- Burger King, another American fast-food chain, published a full-page advertisement in USA Today in 1998 announcing the introduction of the "Left-Handed Whopper," specially designed for the 32 million left-handed Americans. According to the advertisement, the new burger included the same ingredients as the original, but the condiments were rotated 180 degrees. The chain said it received thousands of requests for the new burger, as well as orders for the original "right-handed" version.

-- In 1992, US National Public Radio announced that Richard Nixon was running for president again. His new campaign slogan was, "I didn't do anything wrong, and I won't do it again." They even had clips of Nixon announcing his candidacy. Listeners flooded the show with calls expressing their outrage. Nixon's voice actually turned out to be that of impersonator Rich Little.

-- Noted British astronomer Patrick Moore announced on the radio in 1976 that at 9:47 am, a once-in-a-lifetime astronomical event, in which Pluto would pass behind Jupiter, would cause a gravitational alignment that would reduce the Earth's gravity. Moore told listeners that if they jumped in the air at the exact moment of the planetary alignment, they would experience a floating sensation. Hundreds of people called in to report feeling the sensation.

I've done my share of practical jokes (the good ones I'll never admit to). But, there's always the standard changing the office furniture while someone's on vacation thing. I mean, nothing close to the level of punk'd, but stuff I thought was amusing. Any funny practical joke stories out there?
