Who made Biden — and Katie Couric — look dumb?

It's not Biden's fault — or Couric's — that he — or she — looks like a doofus posing with reality show wannabes at the White House State Dinner. It's not their job to check identities. It's their job — at a party — to pose like this — or is there some gracious way to deflect posers? You might ask why they're throwing big parties when times are so bad. But what the hell? And when can we watch the big Oprah-Obama TV Christmas special? There's Obama putting up the White House decorations, the doorbell rings, and it's Oprah! The doorbell rings again... and it's — who? — Russell from "Survivor"?
