<P> In England a "fool" is known by different names around the country, including a "noodle", "gob", "gobby" or "noddy". </P> <P> In Ireland, it was traditional to entrust the victim with an "important letter" to be given to a named person . That person would then ask the victim to take it to someone else, and so on . The letter when finally opened contained the words "send the fool further". </P> <P> In Poland, prima aprilis ("1 April" in Latin) as a day of jokes is a centuries - long tradition . It is a day in which many jokes are told; various hoaxes--sometimes very sophisticated--are prepared by people, media (which often cooperate to make the "information" more credible) and even public institutions . Serious activities are usually avoided, and generally every word said on April 1st can be a lie, or a joke . The conviction for this is so strong that the Polish anti-Turkish alliance with Leopold I signed on April 1, 1683, was backdated to March 31 . However, for some in Poland prima aprilis ends at noon of April 1st, and prima aprilis jokes after that hour are considered inappropriate and not classy . </P> <P> Danes, Finns, Icelanders, Norwegians and Swedes celebrate April Fools' Day (aprilsnar in Danish; aprillipäivä in Finnish). Most news media outlets will publish exactly one false story on April 1; for newspapers this will typically be a first - page article but not the top headline . </P>
