Once a lamb was drinking water in a mountain stream. A tiger came to drink the water a few yards above him, saw the lamb, and said, "Why are you muddying my stream?"
The lamb said, "How can I be muddying your stream? I'm sown here and you're up there?"
"But you did it yesterday."
"I wasn't even here yesterday!"
"Then it must have been your mother."
"My mother had been dead for awhile. They took her away."
"Then it must have been your father."
"My father? I don't even know who he is!
"I don't care. It must have been your grandfather or great-grandfather who has been muddying my stream. So I am going to east you!", the tiger exclaimed. And with that he pounced on the lamb and made a meal of him.
