Why do jokes make people laugh?

The same is true in life, especially humorous language, which can arouse people's laughter and aftertaste. For example, when we invite friends to dinner, the hostess is afraid that everyone will help us politely. The male host says that we are back in the matriarchal society, and women share the dishes. Everyone burst into laughter. This is not ridiculous at all if it is put at an anthropological academic conference. But the use of technical terms in non-professional scenes was unexpected, and everyone laughed.
