I really want to know what the jokes in the mv are and why everyone laughs after listening to them. Please, 3Q.

MTV: The monster's girlfriend (almost) became a vegetable because of an accident. In order to make money to buy her a beloved jumpsuit, Monster set up a stall in the street to tell jokes. Many people come to listen to the jokes of monsters, including aunts, pregnant women, underworld brothers and even beggars. In Monster's joke, they were all happy for a while, but they were not really happy. A girl in an amusement park cried instead of laughing after listening to the monster's joke. At this time, the smile on the face of the person who heard the joke stopped. The end of the story explains why the monster makes money, which is also in line with the beginning: you think you can make the whole world happy, but you are not really happy. This song mainly tells that every ordinary person has all kinds of unpleasant experiences in real life, which is very appropriate! The joke in MTV is simple: you are not really happy.
