Via BoingBoing, I came across a clip in which the Stephen Fry demonstrates how to get an idiot to hoist himself on his own petard:
Seriously. Not only is this a beautiful sequence, one that can be admired (and dissected) purely for its documentary technique, it’s also a brilliant tutorial on the art of interviewing. Look at how Fry permits his subject to give the viewer precisely what he or she needs to get the point — with never less than perfect politesse from Fry himself. You could call it interlocutory murder — but there’s nary a scrap of blood on our Stephen’s hands.
