April Fools' Day and its many jokes and tricks have been around for a very long time, according to Wikipedia there are references to it in the 15th century 'Canterbury Tales' by Chaucer. (At the online British Library you can even read the original tales from the first edition printed by William Caxton.)
In 1957, the BBC fooled a large part of the nation with its spoof report in the normally-serious Panorama programme about growing spaghetti on trees in Switzerland, while in 1998 the Burger King chain placed an advert in 'USA Today' to launch their left-handed Whopper.

In 2003 a website posted news about a person catching a virus from their computer.

And before someone starts to tell you that Apple machines do not have the same problems that many Windows machines face, you might like to learn that in 1981, the Elk Cloner virus was written to infect the easily-compromised Apple II. It was probably the first large-scale computer virus outbreak in history. (Coincidentally, that happens to be the favoured subject of one Apple 'fanboy'.)
Even your mobile phone can be vulnerable.
