I think this has to be one of the most awkward situations's Ai Shinozaki has been in. Watch the old man keep leering at her boobs; in a way i feel sorry for her. I know she is a gravure idol, but i think she wants to be known for more other than being a girl wth big boobs. plus does anyone else know what DVD they are promoting here?
That guy is a professor that studies Japan current history/culture and has a TV show about it. The DVD was a compilation of said show. How can he be considered an expert in Japan and don't even speak Japanese is beyond weird... so he was in that even just standing there not understanding what people was asking so he just went on to try to be funny... 

It was truly cringe worthy, but it seemed like it may have been a skit and was woefully in poor taste and not written at all well. On the plus side she seemed to handle it rather well, if I were her I would have made sarcastic faces with head shaking and ruined it.
