一天一一位女士在家附近遛弯，碰上一个抱着几个小狗崽的小男孩儿。
“你想要个小狗崽吗？，他们还没有做好准备到一个新家，但是用不了几个星期后就可以了。”
“哦，它们好可爱啊，”这位女士说，“他们是什么品种？”
“它们是经济学家。”
这位女士回家后把这件事告诉她丈夫。这人一听非常想去看看那些小狗崽。大概一个多星期后他碰上那小子，他带的那些小狗崽非常活跃。
“嘿，先生，想要个小狗崽吗？”
“我想我老婆上周和你聊过，你说这些小狗是什么品种？”
“哦，这些是决策分析师。”
“我怎么记得你上周说他们是经济学家。”
“是啊，但是那之后他们就睁开眼睛了。”

One day a woman went for a walk in her neighborhood and came across a boy with some puppies. "Would you like a puppy? They aren't ready for new homes quite yet, but they will be in a few weeks!"
"Oh, they're adorable," the lady said. "What kind of dogs are they?"
"These are economists."
"OK. I'll tell my husband." So she went home and told her husband. He was very interested to see the puppies. About a week later he came across the lad; the puppies were very active. "Hey, Mister. Want a puppy?"
"I think my wife spoke with you last week. What kind of dogs are these?"
"Oh. These are decision analysts."
"I thought you said last week that they were economists."
"Yeah, but they've opened their eyes since then."
