A man in ancient times thought he was clever, but he always did foolish things.

One day, he saw a beautiful bell. It was at the top of a door. “Oh, how nice! I will take it home. ”he said to himself. He thought hard. Then he had a “good” idea. “Aha! I can plug my ears. I will not hear the ring.”
He did so, but the bell rang. The owner opened the door and asked angrily, “What are you doing here?”
