Rush Limbaugh participated in Jay Leno’s “Green Car Challenge” obstacle course Thursday night — and ran over a cutout of Al Gore twice. Limbaugh’s antics cost him time on the course (he recorded the worst celebrity lap yet), but clearly El Rushbo thought the challenge offered greater opportunities than mere lap times. Comical stuff.

Ford has given Jay’s show a sneak peak of its 2011 Ford Focus, a version of which will be battery-powered. With GM reaping PR points for its 2010 plug-in Chevy Volt, Ford is using the launch of car-guy Leno’s new show to preen green.
