Q. How many Sarah Palins does it take to screw in a lightbulb? A. Two! One to wander around the country devouring babies indiscriminately on a large-scale media-whoring expedition, and another to confront the first on a Boston street corner with vaguely threatening intimations that this meeting won't be their last. (Oh, and "one of her guys" to actually change the bulb.) [Video via Hardball]
