The jokes and their victims are calledApril fools. People playing April Fool jokes expose their prank by shoutingApril Fool. Some newspapers, magazines, and other published media report fake stories, which are usually explained the next day or below the news section in small letters. Although popular since the 19th century, the day is not a public holiday in any country. 二、Origins of April Fool’s Day  In 1582,Pope Gregore XIII ordered a new calendar (the Gregorian Calendar) to replace the old Julian Calendar. The new calendar called for New Year's Day to be celebrated Jan. 1. That year, France adopted the reformed calendar and shifted New Year's day to Jan. 1. According to a popular explanation, many people either refused to accept the new date, or did not learn about it, and continued to celebrate New Year's Day on April 1. Other people began to make fun of these traditionalists, sending them on "fool's errands" or trying to trick them into believing something false. Eventually, the practice spread throughout Europe. 三、 Bottom Line of the Day Making jokes only lasts until the noon of the day, the rule is fixed and acknowledged everywhere. Anyone who tries to make a fool after midday is a bigger fool than he who has been fooled. 四、Two Jokes About the Day 1. San Serriffe Image1977: The British newspaper The Guardian published a special seven-page supplement devoted 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 obscure nation. 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 idyllic holiday spot. Only a few noticed that everything about the island was named after printer's terminology. 2. Nixon for President 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.
