Why do we laugh at jokes?

What is the joke? The trick with jokes is to create surprises and deliberately mix things up. You thought you were on the sixth floor, but suddenly the floor was pulled out, and you fell down to the second floor and sat on the ground laughing.

The jokes must be short, refuse to be boring, the ending must be unexpected, have gimmicks, and finally reach a funny climax.

Children laugh about 400 times a day, adults only laugh 15 times. Sometimes I don’t laugh once a day, except this time. When you laugh, your whole body is happy, and the ability to laugh is innate. When you laugh, 18 muscles on your face move. Promotes digestion, accelerates heartbeat, provides sufficient oxygen to the brain, and improves immunity.

In the past, educated people did not dare to laugh. All words will make you smile. Later, cartoons appeared, in which politicians with big noses and fat rich men were both ridiculous and acne-prone. Turns out jokes aren't silly language, just like there's no "only slightly pregnant" thing in real life.

It is said that the East Frisians in Germany are the funniest, and the Germans laugh at them. When they milk the cow, they need four men to hold the cow's udder, and more than twenty men to move the cow; when twisting the light bulb, one person stands on the table and puts the light bulb into the screw, and the four people below turn the table. They also invented reversible toilet paper. The Germans didn't need them to go up the tower either, for fear they would feed people on the plane.

It was later discovered that the East Frisian joke was made up by a radio station in Denmark, Germany's neighbor. It was heard by neighboring Germans and adapted into a joke.

This is why absurd things are interesting. But although the story is ridiculous, it cannot be vulgar or obscene.
