Once there lived a washerman and his donkey in a village. During the day, the donkey would carry the washerman's bags. During the night the washerman would set him free in the field to eat grass. However, the donkey would sneak into nearby farms and eat the fresh vegetables there.
One day, while wandering thus, he met a jackal. They became friends and the donkey invited the jackal to join him on his rendezvous at night. They started meeting every night. By day break, the donkey would be back home.
This went on for many days. One day the jackal said, "Uncle, I have discovered a new field with ripe, juicy cucumbers not very far off. It is nothing less than a feast for you. I am sure I will also find some small animals for myself in that field. Let's go there tonight."
