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

The villagers, seeing that there were many monkeys around, went into the
forest and started catching them. The man very gentlemanly bought thousands
of monkeys at $10 each,but as supply started to diminish, the villagers
slowed down and eventually stopped their efforts.

The man then announced that he would now buy at $20. This renewed the energy
and 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 was then increased to $25 each, but the supply of monkeys became
so little that it was a almost a miracle to even spot a monkey, let alone
catch one.

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 transact on his
behalf.

In the absence of the man, the assistant assembled the villagers and told
them : " Look at all these monkeys in the big cages that the man has
collected. I will sell them to you at $35 each, and when the man returns
from the city, you can in turn sell them to him at $50 each. Deal or no deal
? "

The excited villagers, smelling a quick-profit killer opportunity,
immediately rounded up all their savings and bought all the monkeys. Then
they never saw the man nor his assistant again, and there were just monkeys
everywhere!
