The cable news channels have been falling all over themselves for the last few days, desperate to find something new to say about the JonBenet Ramsey fracas. Meanwhile, what do you suppose the lead story was on yesterday’s edition of The Colbert Report? Grigory Perelman’s refusal of the Fields Medal for his proof of the Poincare conjecture. Not only that, but Colbert even got the math right. An impressive performance, and another sad reminder that Comedy Central is just about the only place on television for serious news.
