"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."
