Please tell a joke with "you", "me" and "he (she)".

There is a child who teaches me on the first day of school. You and him, for example, I am your teacher, you are my student and she is your classmate. When the child came home, his parents asked him what he had learned. He said he learned from me, you and him, for example: I am your teacher, you are my student and she is your classmate. Dad shouted wrong and said, I am your father, you are my son, and she is your mother. The next day, the child said to the teacher, you were wrong yesterday. I am your father, you are my son and she is your mother. The teacher fainted. Ha ha. . . .
