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