In class today, the teacher flew into a rage as soon as he saw Tom's exercise book. Holding back his anger, he called Tom to the podium and said seriously, "Tom, why did you do your homework so badly?" Go back and get your dad to sign it and see what he can do to you! "Tom's head drooped like a withered eggplant. He even heard the ridicule of his classmates below. Tom is very depressed. what can I do? If dad saw it, why didn't he beat him to pieces?

After school, Tom walked dejectedly, thinking about countermeasures while walking, and soon came up with a "trick". He hurried home. As soon as I entered the door, I pretended to be calm and said to my father, "Dad, let's play a game. Let me show you first. " Then he put down his schoolbag, found a scarf to cover his eyes, picked up a pen and fumbled for his signature on the paper. As he wrote, he asked his father, "Dad, what do you think of my signature? Can't you? " "What's the matter!" As expected, dad was taken in. Then he took off the scarf from Tom's eyes, put it over his eyes, and practiced sign language on the ground like Tom. Tom seized the opportunity, crept to the front of his schoolbag, took out his exercise book and carefully put it in front of his father who was still in the dark and continued to write! After his father signed his name, Tom quickly put his exercise book back in his schoolbag.

Seeing the success, Tom said with relief, "Dad, the game can be over." Dad took off his scarf and admired himself at the signature. Looking at it, he was a little puzzled and said to himself, "Obviously, four words have been signed, how come there are only three left?" When Tom looked at his father Zhang Er, he made a face proudly, which puzzled the monk.
