A whoopee cushion is a classic practical joke toy that makes a funny sound when someone sits on it. It is usually made of rubber or plastic and is inflated with air. When a person sits down, the air escapes, creating a loud, flatulent noise that surprises everyone nearby. This silly sound is what makes the whoopee cushion a favorite among kids and adults alike. Invented in the 1920s, the whoopee cushion has become a staple in the world of practical jokes. It’s often used at parties or gatherings to get a laugh. Many people associate it with childhood fun and lighthearted mischief, making it a timeless gag gift.
