Ricky was at the mall and went into a toy shop, picked up a toy plane, gave the shopkeeper Monopoly money and started to leave.
The shopkeeper told him, “Excuse me little boy, this isn’t real money.”
Ricky continued walking out of the shop and didn’t reply.
The shopkeeper repeated himself, and Ricky kept walking.
The third time the shopkeeper called him, Ricky said “What?”
The shopkeeper said, “I’m sorry, young man, but this is not real money.”
Ricky looked at the plane in his hands, looked at the shopkeeper and finally said, “And this isn’t a real plane.”
