A practical joke is a playful trick or prank intended to amuse or surprise someone. It often involves setting up a situation that leads to an unexpected outcome, usually resulting in laughter. Common examples include fake spiders, whoopee cushions, or harmless surprises that catch the target off guard. While practical jokes can be fun, they should be executed with care to avoid causing distress or harm. The best practical jokes are lighthearted and considerate, ensuring that everyone involved can enjoy the humor. Famous pranksters like Johnny Knoxville and shows like Punk'd have popularized this form of entertainment.
