Little Johnny went to the mall and hurried to a toy store to get a toy plane. He gave the store Monopoly money and began to leave. The shopkeeper informed him, “Excuse me, little boy, this isn’t real money.”

Little Johnny continued going out of the shop without responding. The merchant repeated himself, and Little Johnny continued walking. The third time the shopkeeper called, Johnny answered, “What?”

The shopkeeper replied, “I’m sorry, young man, but this is not real money.” Little Johnny glanced at the plane in his hands, looked at the merchant, and then stated, “And this isn’t a real plane.”
