Dubner on “Good Morning America”

ABC News, in its infinite wisdom, has signed up Levitt and Dubner as regular Freakonomics contributors to its various programs (Good Morning America, World News Tonight, and 20/20). The next installment will be on Friday, Jan. 27, when Dubner visits G.M.A. (between 8:00 and 9:00 a.m.) to discuss a topic which cannot be revealed here but which is certifiably freaky.
