愚人节，这个来自西方的节日，如今也是一个家喻户晓的节日了。这或许是众多节日里最让人担心吊胆的一个了吧!每当4月1号来到的时候，大家都绷紧了一根弦生怕一个不小心就被人给愚弄了，但同时又在想方设法的研究着怎么去愚弄别人。

　　愚人节开的玩笑基本都是挺逗人的，没什么恶意。明的愚人节玩笑能让在场的每个人都捧腹大笑，即使是那个被作弄的人也会忍俊不禁。正如美国幽默作家马克吐温所说的“只有在四月的天，我们才记起在过去一年的364天中我们是多么的愚蠢”。不过，不管是愚弄人还是被人愚，这都会给我们带来了无限的欢乐!

　　April 1 In sixteenth-century France, the start of the new year was observed on April first. It was celebrated in much the same way as it is today with parties and dancing into the late hours of the night. Then in 1562, Pope Gregory introduced a new calendar for the Christian world, and the new year fell on January first. There were some people, however, who hadn't heard or didn't believe the change in the date, so they continued to celebrate New Year's Day on April first. Others played tricks on them and called them April fools. In France today, April first is called Poisson d'Avril. French children fool their friends by taping a paper fish to their friends' backs. When the young fool discovers this trick, the prankster yells Poisson d'Avril!

　　Today Americans play small tricks on friends and strangers alike on the first of April. One common trick on April Fool's Day, or All Fool's Day, is pointing down to a friend's shoe and saying, Your shoelace is untied. School children might tell a classmate that school has been canceled. Whatever the trick, if the innocent victim falls for the joke the prankster yells, April Fool!

　　Most April Fool jokes are in good fun and not meant to harm anyone. The most clever April Fool joke is the one where everyone laughs, especially the person upon whom the joke is played.American humorist Mark Twainthe has siad that the first of April is the day we remember what we are the other 364 days of the year.
