1996年愚人节，塔可钟快餐公司说他们买下了美国费城独立厅的大钟，并重命名为塔可自由钟。愤怒的市民打电话给费城的国家历史公园，要求确认这个消息。几小时后塔可钟快餐公司承认这只是个玩笑。当天最乌龙的事件还不在此。白宫记者会秘书Mike McCurry被问到这件事时，随机应变回答说，林肯纪念碑也被卖了，现在被命名为福特水星汽车纪念碑。
这位秘书真有娱乐精神。咱也可以说，张家界的“哈利路亚”山被外星人收购了……
San Serriffe
虚拟国家
image1977: The British newspaper The Guardian published a special seven-page supplementdevoted to San Serriffe, a small republic said to consist of several semi-colon-shaped islands located in the Indian Ocean. A series of articles affectionately described the geography and culture of this obscurenation. Its two main islands were named Upper Caisse and Lower Caisse. Its capital was Bodoni, and its leader was General Pica. The Guardian's phones rang all day as readers sought more information about the idyllicholiday spot. Only a few noticed that everything about the island was named after printer's terminology.
1977年愚人节，英国卫报发行了长达7页的增刊，全是介绍San Serriffe这个印度洋上的小岛国的，据说那里有好几个分号形状的小岛。文章中大肆渲染了这里的风情和民俗，介绍了它的城市和首都，甚至总统的名字。当天卫报编辑室的电话都被读者打爆了，大家都想知道这样美好的度假胜地在哪。只有少数人注意到，首都名字Bodoni是印刷术语，是一种印刷字体的名称。
非常安全无害的玩笑，有创意有文采。
Nixon for President
尼克松复出
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.
1992年愚人节，全国公共广播电台宣布，尼克松又要竞选总统了，他的竞选宣言是：我没做错事；我也不会再做错事。新闻中还穿插了一段尼克松的讲话。愤怒而惊讶的听众纷纷打电话来质问。随后主持人承认这是假的，尼克松的声音也是一个喜剧演员模仿的。
不知道这回美国人还会不会拿自己的总统做文章？
Alabama Changes the Value of Pi
圆周率值的修改
1998: 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 'Biblicalvalue' of 3.0. Soon the article made its way onto the internet, and then it rapidly spread around the world, forwarded by 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 circumscribethe teaching of evolution, was written by physicist Mark Boslough.joozone.com
