The Crow and the Pitcher

One day a crow became thirsty. He was looking for water. He found no water anywhere. At last he saw a pitcher. He came to it. He saw water only at the bottom of the pitcher. He could not drink. He hit a plan. He Saw pebbles lying near by. He picked up the pebbles and dropped them into the pot. The water level rose high. Now the crow drank water at ease.
