What is Zhu's intention in telling his mother a beggar joke in his essay?

1. A beggar said to another beggar, "Do you know? In fact, I am a fallen hero. I think I was a sprint champion that year. "

Another beggar looked envious and asked, "When did this happen?"

The beggar replied, "When I became a sprint champion, I rested in my mother's stomach."

Three beggars didn't eat for several days, so they bragged together. The first beggar said, "I'm really hungry. Now I can't eat enough even with a hundred pieces of bread! " The second beggar also said, "I'm really hungry." Now even if you give me a bread mountain, I can't eat enough! "The third beggar said nothing. In front of the first two beggars, he took out a mass of black sticky substance from his nose and chewed it in his mouth. At this time, the first two beggars vomited for a while, and the three beggars said in unison, "I'm full!" " "

A beggar went to the door of a rich man's house to bask in the sun, and the rich man sympathized with him. So he called the beggar and said, "Little beggar, I can give you some money, but you must help me move the 100 brick behind." I am defending your dignity, I will eat whatever I have! " So the little beggar agreed happily. The little beggar worked in the rich man's backyard for a long time and finally moved out. The rich man was very happy and gave him a red envelope.

The little beggar walked out of the rich man's house and opened the red envelope, only to find that there was a check with 654.38+00,000 yuan in it.

The little beggar was very angry. He tore up the check and cursed, "Fuck, how much can you write on a piece of paper?" Bullying me is illiterate. "
