A few days ago I encountered a blog comment in which a liberal retold the Tina Fey 'joke.' for the millionth time. As usual there was no indication that he knew it was a joke. "Sarah Palin said that she could see Russia from her house!" has now joined "Bush served a plastic turkey to troops in Iraq!" and "Dick Cheney outed Valerie Plame as a CIA Agent!" in the Compendium of Irrefutable Liberal Facts.
