Once there was a fox and a tiger in a forest. One day, they met each other.
Tiger: I'm hungry and I am going to eat you.
Fox: But there is another tiger in the forest. And he said he was stronger than you.
Tiger: Where is he? Show me. The tiger followed the fox to the river.
Fox: Look, there is another tiger in the river. He is stronger than you.
Tiger: No! I am stronger!
The tiger was angry and wanted to catch the other tiger. And he jumped into the river.
The fox laughed happily and left.
