"Top 100 April Fool's Day Hoaxes of All Time" to stir the brain cells...
http://www.museumofhoaxes.com/hoax/aprilfool/#6: Nixon for President
In 1992 National Public Radio's Talk of the Nation program announced 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.
#7: Alabama Changes the Value of Pi
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. Before long the article had made its way onto the internet, and then it rapidly made its way around the world, forwarded by people in their 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 a physicist named Mark Boslough.
#8: The Left-Handed Whopper
In 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."
#9: Hotheaded Naked Ice Borers
In its April 1995 issue Discover Magazine announced that the highly respected wildlife biologist Dr. Aprile Pazzo had discovered 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.
#10: Planetary Alignment Decreases Gravity
In 1976 the British astronomer Patrick Moore announced on BBC Radio 2 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 that 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.

I love Bill Bored's idea, but we'd need to make up a serious-sounding civic or historical group to propose making April 1 into Election Day. The Society for the Prevention of Dictators Becoming President. Something like that.

The origin of April Fool's day seems to date back to a change made by the Church in Rome from the Julian (Pagan) calendar to the Gregorian (Catholic) calendar, in 1582. April Fool's was the Pagan celebration of the New Year, in late March/early April. The Gregorian calendar changed the date of New Year's to Jan. 1 (and changed late March/earlyApril to the mourning of the passion and death of Christ and the Easter celebration of his resurrection from the dead). But many people resisted this change, and continued with their Pagan celebrations of spring. The Christian establishment took to playing jokes on those who forgot or who defied the change--false invitations to parties, and so on (wild goose chases), and other kinds of tricks.
So it would seem to be a Christian holiday--a day to play tricks on clueless Pagans. However, when I was young, I was told that April Fools' was a Pagan tradition and that "the Fool" meant Jesus Christ, who was foolish to die for our sins. Apart from the wisdom of that--I mean, given the totality of human sins, you have to wonder about someone who would take on all the punishment for them--what the teller of this myth meant was that Pagans were mocking Jesus (rather like the Roman soldiers who were said to have mocked his pretention to kingship with the crown of thorns). As young Catholics, we weren't supposed to play April Fool's tricks. (It was making fun of Jesus.)
Take your pick, I guess--anti-Pagan, or anti-Christian. Somewhere in here is a nifty April Fool's trick for George Bush and that minority of Americans who voted for him.
