Share interesting things about life, what humorous but not vulgar jokes or?

After school, my son excitedly shared an interesting story. A child in the class went to school in the afternoon and found that his pants were on backwards. Later, he went to the bathroom to change. He went back to the classroom and said that he was wrong again, and then he went to the bathroom to correct it. The result was still wrong, and he didn't go back to correct it. The son was talking and laughing. I watched his hand in his trouser pocket, because the trouser pocket was at the back. I said your pants are on backwards and your hands are still inside. My family immediately burst out laughing.
