A joke novel with a funny ending.

1. Dad went into his son's room and praised him: Well done, son! The windows are clean and bright. Did you wipe it with soapy water? Son: No, Dad, I used a hammer. The primary school started, and my son who just turned 6 refused to go to school. The mother explained to her son that the child would go to school at the age of 6 until 15. Finally, my son sat at his desk with tears in his eyes and asked: When I was 15 years old, did you remember to pick me up? 3. When my son was in the fifth grade of elementary school, his father heard that he participated in the extracurricular "couplet interest group" and made a couplet, trying to get him to match: "Father has father, son has father, father and son are divided into two generations"; The son thought about it and quickly made a couplet: "I have children, my father has children, and my father is a family." Dad: "My first couplet contains all ages and order." The son replied, "My next couplet is the same size." 4. When the son came home, he said to his father, "Dad, people say that you have both beautiful language and beautiful behavior." Father was very happy and asked, "What did they say?" The son said, "They say you speak better than you sing. This is called "American English". He also said that you' played the fake like the real thing', which is called' behavioral beauty'. "
