I collect economics jokes, not jokes about economics but jokes that teach economics. It is a very small collection. I had three when I wrote my Price Theory, all of which I included. I later discovered a fourth in a middle eastern cookbook by Claudia Roden:

What is sweeter than honey?



Free vinegar.

I have just found a fifth in Leo Rosten's The Joys of Yiddish, following his definition of frosk as a slap:

"My father was so mad yesterday," said little Morris, "that five separate times he wanted to give me a frosk."



"How do you know it was exactly five time?"



"Because I counted."



"What did you count?"



"The number of times he hit me."



"I thought you said he wanted to hit you."



"I did. Would he have hit me if he hadn't wanted to?"
