A 3-minute speech, jokes, fairy tales and idiom stories will do.

One day, a butcher was busy in the shop when suddenly a dog ran in. The butcher hissed and drove the dog out. But in a short time, the dog ran back. The butcher felt a little strange. He looked intently and found a bag in the dog's mouth, and a note was exposed outside the bag. The butcher opened the note and saw that it said, "I want to buy 12 sausage and a leg of lamb." The money is in the bag. " The butcher looked at the bag: there is the money. So he put the money away and put sausages and leg of lamb in the bag. At this time, it's almost time to close the store. On a whim, the butcher closed the shop and followed the dog, and decided to go and have a look. The dog leisurely crossed a street and came to a crossroads. It put down the bag in its mouth, jumped up and pressed the traffic light button next to it with its claws. Then it squatted on the ground and waited patiently for the green light, then picked up the bag and crossed the road. The butcher followed closely. Then, the dog walked to a bus stop sign. It looked at the timetable. The butcher was stunned by its action. Knowing the time, the dog squatted in a nearby seat and waited for the bus. Soon, a bus came, and the dog quickly stood up to see if it was wrong and returned to his seat. A few minutes later, another one came. The dog stood up, looked at the train number, found that he was sitting right, and climbed into the car. The butcher opened his mouth wide in surprise and jumped into the car. The bus goes through the city to the suburbs. On the road, the dog quietly looked at the scenery outside the car. After a long time, it stood up, walked to the back door, waited for the bus to stop, and jumped out with a bag in its mouth. The dog came to a house by the road. It put down the bag in its mouth and knocked on the door for a while with its claws. No one answered, so it knocked on the door again and again. But no one answered the door, so the dog jumped on a low wall next to it, then jumped into the garden, climbed up the window, hit the window with his head several times, and then went back to the door and squatted on the ground and waited quietly. The butcher looks more and more confused. Just then, suddenly the door opened and a big fellow came out, raised his foot and kicked the dog hard, cursing while kicking. The butcher was angry. He rushed up and angrily reprimanded the big fellow: "What the hell are you doing? What a clever dog this is! You can definitely become a TV star! " The big fellow sneered and mocked at him: "Smart? God, this is the second time this week that he forgot his key! "
