I know zip about Harry Potter. Haven't read the books, haven't seen the movies. So I didn't pay a whole lot of attention to Keith Olbermann's segment tonight offering his theory as to how the series will end. Since then however, five different people have written me to say that it's a terrific, logical guess. If you'd like to hear this terrific, logical guess, you can view the segment here. And keep in mind that all terrific, logical guesses as to how The Sopranos would end were wrong.
