English Original
A dog owner claimed that his pet, when given money, would go to the news stall to buy a newspaper. His friend insisted on a demonstration and handed the dog some money. The dog trotted off, but an hour later, it had still not returned with the paper.
"How much did you give him?" asked the owner.
"Five dollars."
"Well, that explains it. When you give him five dollars, he goes to a movie."
