John McCain’s been dodging a lot of his responsibilities as of late. For starters, he’d like to put his campaign on hold, and for seconds he bowed out on his Letterman appearance last night. The Letterman camp was not about to take this lying down. Nobody, especially candidates for the presidency, leave the couch empty. Letterman sent his spy dogs out on the trail, and found McCain conducting an interview with Katie Couric while he was supposedly “on a plane to Washington D.C. to fix the economy.”

Nicole Richie was at The Late Show with David Letterman last night and she revealed that she’s scared to go to jail like her Simple Life co-star, Paris Hilton.

Nicole Richie pleaded not guilty in February to DUI on Dec. 11.
