How Many Chicago School Economists Does It Take To Change A Light Bulb?

The American Antitrust Institute provides this short essay describing some of the best (or worst) antitrust law jokes. The essay was prompted by a speech by Attorney General Alberto R. Gonzales in which he "reported that after a team of researches had worked 'furiously for days,' he could 'confidently report' 'that there are no jokes about antitrust law.'" By the way, the punch line to the joke in the title of this post is: "None. If the light bulb needed changing the market would have already done it."
