One evening two German were walking in the street together. They tried to find a chance steal something. The clock struck 12. Most of the people had going to bed. Quietly they came to a house. There were no lights in the house but it seemed that everyone in the house were asleep. Standing at the front gate, one said in German to the another, "You wait here. I'll go around to the back door and then get into the house..." Suddenly out of the house ran a dog. The two men were frightening and ran away as fast as they can. They dared not to stop until they got to a lonely place "I hadn't expecting the dog could understand German," one man said.
