Leo Rosten on Revealed Preference

I have a very small collection of economics jokes, not jokes about economics but jokes that teach economics. Browsing Leo Rosten's The Joys of Yiddish, I found another one: -->

"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 times?" "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?"

----A reader who remembers my past posts better than I do points out that I blogged this joke once already, a couple of years ago.
