How ironic that I am writing about this on April 1--- a day known in many countries of the world as April Fools Day. Chaucer's Canterbury Tales (1392) is thought by many as the origin of this interesting observance. Others argue that the Iranian day known as Sizdah Bedar (536 BC) where people play jokes and pranks on each other is really the true origin of April Fool's Day as we know it today. Regardless, it is amusing to learn how different cultures observe the day. French speaking people (including French Canadians) as well as Italians, historically tacked paper fish on the backs of unsuspecting victims hoping not to be caught in the act. Often April 1 was a day of pranks and practical jokes. Many times instructions were given to go somewhere for a special event that did not exist. An example is an April Fool's announcement from April 1, 1857 announcing the supposed washing of the lions at the Tower of London pictured below.
