A fox observing a fish cart coming, lay down and pretended to be dead.
The cart man, tempted by the idea of making some money by selling the fox's fur, picked up the animal by its tail and flung it into the back of the cart among the fish.
Then he resumed his journey
The fox ate his fill of the fish and jumped out of the cart.
A wolf saw him jumping out and asked him what he had been doing in it
The fox told him and also how he had got into it in the first place.
The wolf ran ahead of the cart and lay down in its path, pretending to be dead.
The cart man was delighted to find another animal to sell, but he found the animal too heavy to lift.
So he pushed it into a sack, tied the sack to his cart and dragged it away.
Moral: What works for one may not work for another.
