Top 5 Pranks
A practical joke is a mischievous trick played on someone, generally causing the victim to experience embarrassment, perplexity, confusion or discomfort. A person who performs a practical joke is called a practical joker. Other terms for practical jokes include prank, gag, jape, or shenanigan.
Practical jokes differ from confidence tricks or hoaxes in that the victim finds out, or is let in on the joke, rather than being talked into handing over money or other valuables. Practical jokes are generally lighthearted, reversible and non-permanent, and aim to make the victim feel foolish or victimized to a degree. However, practical jokes performed with cruelty or as part of the deliberate exclusion of someone from the in group can become bullying.
In Western culture, April Fools Day is a day traditionally dedicated to conducting practical jokes. (source : wikipedia)
