An Intelligent Crow

“Once upon a time there was a crow. He was very thirsty. He flew angrily here and there to find out water. Eventually, he saw a jug having very little water in it. But the level of water was very low and he couldn’t drink it. He thought an idea for water to come up; he put few stones in the jug. The water came up; he drank it and flew away happily.”
