A practical joke (also known as a prank or gag) is a mischievous trick played on a person, especially one that causes the victim to experience embarrassment, indignity, or discomfort. Practical jokes differ from confidence tricks in that the victim finds out, or is let in on, the joke rather than being fooled into handing over money or other valuables. Practical jokes or pranks are typically lighthearted and made to make people feel foolish or victimized to a certain degree, although in some practical jokes there could be an inherent strain of cruelty present.
