Have you ever played a joke on someone and then, just when that person has fallen for it, said "April Fools!"? April 1 is known as April Fools' Day, and, although no one really knows how the holiday began, it's a great chance to play a joke on someone--as long as the joke is harmless. April Fools' Day gives everyone a chance to play "the fool." In France the fooled person is called poisson d'avril ("April fish"), and in Scotland the person is called a gowk (cuckoo), the symbol of a simpleton.
