When you’re interviewing someone who’s used to being the interviewer, as Howard Stern was on The Late Show Monday night, the narrative flips pretty quickly. For instance, Stern grilled the producer on why in the world they would ask Jay Leno to be on Dave’s couch for the last week (he declined), and then asked Letterman who his favorite guest ever was. Letterman pretty masterfully dodged these questions, including the kiss on the mouth Stern was hell-bent on giving him.
