By far the most amusing detail to emerge from the Wednesday morning arrest of Al Gore III, son of the Oscar-winning ex-Vice President behind eco-porn masterwork An Inconvenient Truth, is that the young Gore was driving a Prius; no matter how upset Dad was by the phone call revealing that his child had been popped for the possession of marijuana and enough prescription drugs to sedate a typical Orange County housewife for a week, he had to be at least a little bit proud that his boy is doing his part to reduce the dangerous vehicle emissions that have brought our planet to the brink of environmental disaster.
