Can you think of anything more inviting than a good knock-knock joke? Who can resist answering “who's there?” after hearing someone say “knock knock”? You'd be hard-pressed to find someone who doesn't love these jokes.
Knock-knocks are popular in every country where people speak English, including the United States, Canada, Great Britain, and Australia. That's because each knock-knock joke is a pun, or a play on words, and puns are more popular in English than they are in other languages.
So, what's the purpose of a knock-knock joke anyway? Well, that's easy! To make you laugh, of course! A good laugh can have many truly wonderful results. Laughter is a universal language that all humans share no matter where they live or how old they are. Laughter can connect people of all ages around the world. Did you know that babies start laughing when they're only two months old? That's so much earlier than speaking or even crawling. Babies know funny when they see or hear it. And so do the rest of us.
Another fabulous result of a good laugh is that it really is the best medicine. Laughter is a great cure when you're down in the dumps and just can't shake the blues. Even the experts agree: Laughter helps to keep us healthy and happy. Science shows us that laughter increases the amount of oxygen running through our blood, makes us relax, and helps us feel less nervous during stressful times. This is no secret. People have known this for centuries. Some people even make a living just getting others to laugh!
Back in the very old days, court jesters appeared before the king and queen just to amuse them. Today, comedians, clowns, actors, and actresses all work hard to come up with funny material to get a good laugh from their audiences. Sometimes people will go out of their way to find something that will make them laugh. They watch movies, go to the theater, and turn on the television set, all in the hopes of kicking back and seeing how funny life can be!
Laughter makes people happy, and we all know that everybody likes to be around happy people. So start chuckling, giggling, guffawing, or even rolling-on-the-floor belly laughing. Gather some friends and start your own hysterical society. This is a group that gets together to tell each other jokes, riddles, and rhymes, act silly, and just plain make each other laugh. Don't worry if no one's laughing right away. Laughter is contagious. Just start tee-heeing, ho-ho-ing, and ha-ha-ing, and everyone else will soon follow.
