DESCRIPTION
April Fools' Day or April Fool's Day (rarely called All Fools' Day[1]) is an annual custom in many Western countries on the 1st of April consisting of practical jokes, hoaxes, and pranks. Jokesters often expose their actions by shouting "April Fool[s]!" at the recipient. Mass media can be involved with these pranks, which may be revealed as such the following day. The custom of setting aside a day for playing harmless pranks upon one's neighbor has been relatively common in the world historically.[2]
