April 1 is April Fools' Day, an annual custom when people practice various pranks and practical jokes, often with jokesters shouting, "April Fools!" at the recipient of a successful prank. In many places, the pranking traditionally ends at noon, with pranks performed after that time considered in bad taste and the prankster instead of the victim being considered the "April fool".
