April 1st is the day people try to trick their friends, to make them behave like fools. Ranging from the elaborate practical joke to the obvious Your zip's undone. If you fall for a prank, the joker gloats "April Fool". No one is exempt until noon, but after that the joking must cease or the prank rebounds on the joker with the rhyme "April Fool is gone and past, You're the bigger fool at last." A favourite joke is to send someone on a fool's errand, a search for something that does not exist, a friend of mine was sent to buy tartan paint once.
