How many Republicans does it take to screw in a lightbulb? Four hundred and sixty-two: Twelve to investigate Clinton's involvement in the failure of the old bulb, twenty-three to deregulate the light bulb industry, sixteen to cut funding for alternative lighting R&D, thirty-four to cut the tax rate on light bulbs, fifty-three to design a block grant so the states can change the bulb, forty-one to talk with defense contractors about night-vision gear instead, and two hundred and eighty-three to pass a law making it illegal to discuss naked bulbs (or screwing anything) on the Internet.
