I use slides

I had to chuckle when The Times's David Carr compared Glenn Beck to a macroeconomics professor in an article today:

What had been a fast and loose assault on all things liberal has grown darker and less entertaining, especially with the growing revolution in the Middle East, a phenomenon Mr. Beck sees as something of a beginning to some kind of end. He’s often alone in the studio with his chalkboards and obscure factoids, a setting that reminds me of an undergrad seminar on macroeconomics with an around-the-bend professor I didn’t particularly enjoy.
