Once upon a time in a village, a man appeared and announced to the villagers that he would buy monkeys for $10 each.

The villagers, seeing that there were many monkeys around, went into the forest and started catching them. The man bought thousands at $10 and, as supply started to diminish, the villagers stopped their effort. He further announced that he would now buy monkeys at $20 for each.

This renewed the efforts of the villagers and they started catching monkeys again. Soon the supply diminished even further and people started going back to their farms. The offer increased to $25 each, and the supply of monkeys became so small that it was an effort to even find a monkey, let alone catch it!

The man now announced that he would buy monkeys at $50! However, since he had to go to the city on some business, his assistant would now buy on behalf of him.

In the absence of the man, the assistant told the villagers. “Look at all these monkeys in the big cage that the man has collected. I will sell them to you at $35, and when the man returns from the city, you can sell them to him for $50 each.” The villagers rounded up all their savings and bought all the monkeys.

They never saw the man nor his assistant again, only monkeys everywhere!
