One day a fox and an ass were passing through the street. They were in search of food.
After going some distance they saw that a lion was standing nearby.
In order to save himself the fox rushed towards the lion. He told the lion, “Sir, I am bringing the foolish ass before you. But you have to leave me.”
The lion agreed to fox’s proposal.
So the fox went to the ass and put him under a trap.
Seeing this, the lion thought the ass could not come out from the trap. So it will be better to grab the fox first.
