Bill O’Reilly appeared on Letterman last night — and as anyone could predict, as soon as the conversation shifted to electric cars, the jabs came quick and heavy.

When Letterman wondered aloud where all the electric cars were, O’Reilly mentioned the Chevy Volt — to which the host immediately dismissed as only a hybrid. “It can go only 40 miles on electric alone, I’d have to recharge it to pick up my mail,” he said, recycling a stale joke used previously. (For the record, nobody mentioned the Nissan Leaf.)

The conversation then shifted to Letterman’s ownership of an electric car — presumably the Tesla Roadster that he picked up a few years back. He did that particular groundbreaking vehicle no favors by not answering O’Reilly on “is it fast?” and “is it a good car?” and later saying that he was an “idiot” for buying one.
