Tonight, Stephen Colbert opened the Report with talk of an imminent due date. No, not Tuesday's debt deadline, the one tomorrow night on Facebook for drivers of Nissan's electric car, the Leaf, to submit ideas for an official gesture to "wave" at fellow owners on the road. Which is lame and sad, of course, but nothing compared to the secondhand embarrassment you'll feel after making it to the end of Colbert's segment.
