How to tell a joke is funny?

1, choose the right person. Some people have no sense of humor at all. If you tell him a joke, either he doesn't understand what it means, or he explains what he understands, just like telling it to vegetables, so it's best not to tell jokes to people without humor. You will be very depressed. 2, language simplification: the language of telling jokes should be simplified, jokes are an art, and no one will laugh if you drag them, but it will give people a feeling of being a fool. 3, the content is novel: old jokes, heard a hundred times, who will find it funny? 4, pay attention to form: for example, the use of contrast before and after, repeatedly causing strong effects.
