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, he had still not returned with the paper.
"How much did you give him? "asked the owner.
"Three dollars."
"Well, that explains it. When you give him three dollars, he goes to a movie."
三元
一位养狗人声称，要是给他的爱犬一些钱，它便会到卖报亭买份报纸来。他的朋友坚持要来个演示，并给了狗一些钱。狗一溜小跑着去了。但一个小时过去了，仍不见它带报纸回来。
“你给了它多少钱？”狗的主人问。
“三元。”
“这就是了。你给它三元钱时，它就会去看电影。”
