I've noticed this several times recently, including when that woman comic was on yesterday. He'll get to what seems to be the end of the interview and start saying goodbye and talking about their upcoming gigs, then all of a sudden he'll start repeating questions he already asked earlier and dragging it out several minutes longer (well past the point it stopped being entertaining). WTF is going on with him? Does he have a specific amount of time he wants to kill no matter how boring the interview is? Does he have Alzheimers and doesn't remember he already asked those questions? Really odd and annoying since you think the torture is about to end and it just keeps going. His interviews are awful.
