interview for the former president. as you mentioned, a very unusual guest host, prince harry of wales. it was actually shot last september on your side of the pond in toronto for the bbc and just released today. if for no other reason, the interview was interesting because of this odd couple it presented. the former u.s. president has taken on a much less public role since he left office. this is really his only real interview, although he's hit campaigns for different candidates, the only real interview since leaving office. meanwhile, this young royal, prince harry, has actually stepped into a far more public role. he just became engaged to american actress meghan markle and the two will be married in may. if there's any one man who's more famous than barack obama at this point it could be prince harry. the two delivered a pretty light-hearted back and forth. take a listen. >> boxers or briefs? >> sorry, we don't answer those
