Practical jokes are playful tricks or pranks that people play on each other for fun. They often involve surprising someone in a light-hearted way, like hiding a whoopee cushion on a chair or pretending to spill something. The goal is to create laughter and amusement, not to hurt anyone's feelings. These jokes can be simple or elaborate, and they often rely on the element of surprise. Famous examples include the classic April Fools' Day pranks, where people try to outsmart each other with clever tricks. When done in good spirit, practical jokes can bring friends closer and create lasting memories.
