“Going green” is a hot topic these days, as companies across the board try to cut their carbon footprint.  (That’s a hot term, too- “Carbon footprint.”)  So Tuesday night, the Governator himself appeared on the Jay Leno Show, and they took part in a “Green Car Challenge.”  Leno does a deadly impression of  Ah-nold, who then terminates Jay with some heavy weaponry. Hope they had insurance on that Focus.
