So, the shopkeeper told him " Hey you, this aint real money", little Johnny (continue walking out of the shop) didn't reply. The shopkeeper said the same thing and the same thing happened, the third time the shopkeeper called him. Little Johnny said "What?" the shopkeeper said "This aint real money" and Little Johnny finally said "And this aint a real plane."
