In an ancient kingdom, there was a very wealthy and wise King. He was very clever too. One day he put a huge rock in the middle of the road and hid in the nearby bush. He wanted to see if anybody try to push it out of the road.
His wealthy merchants passed by the road without touching the stone. Then his soldiers came. Instead of pushing the stone aside they cursed and scolded the king for not properly maintaining the road.
The day passed by and now it was evening. A very lean and thin farmer was coming with his hands full of vegetables and a spade. When he saw the rock lying between the road he kept his things aside and began to push it. The rock was very heavy for him. But with great efforts be was able to get it out of road.
He was about to leave with his belongings when he saw a purse lying in the place where the rock was. He opened the purse and found it stuffed full of gold coins. And there was a letter written by the king that the coins belongs to the person who will remove the rock from the road.
