A practical joke or prank is a trick played on people, generally causing the victim to experience embarrassment, perplexity, confusion, or discomfort. The perpetrator of a practical joke is called a "practical joker" or "prankster". Other terms for practical jokes include gag, rib, jape, or shenanigan. Some countries in western nations make it tradition to carry out pranks on April Fools' Day and Mischief Night.
