A king ordered a boulder to be put on a route in ancient times. He then went into hiding and waited for someone to lift the boulder out of the path. Some of the king's wealthiest merchants and courtiers simply strolled by it.
Many people voiced their displeasure with the King for failing to maintain the roadways free, but none of them did anything to remove the stone.
Then a peasant with a load of veggies appeared. When the peasant arrived at the boulder, he laid down his burden and attempted to push the stone out of the way. He finally succeeded after much pushing and straining.
When the peasant returned to collect his veggies, he discovered a pocketbook in the path where the boulder had been.
Many gold coins were in the purse, together with a note from the King indicating that the reward was for the person who removed the boulder from the path.
