Well, the above is quite a treat...not sure how long it will stay up, though. The show is "Pa-Pa-Pa-Pa-Puffy", Ami and Yumi's own late-night variety show on TV Asahi that lasted for about 2.5 years. I distinctly remember where the stuttery title came from. It just happened to be when Puffy appeared on the old Fuji-TV music program "Hey Hey Hey Music Champ", and co-host Hitoshi Matsumoto（松本人志）of comedic duo Downtown was doing his usual riff at the guests' (cordial) expense. At one point, in a stream-of-consciousness moment, he just blurted out "Pa-Pa-Pa-Pa-Puffy!" Not too long after, buoyed by Puffy's growing popularity, the quip became a title.
Oops...and I have digressed from the point of the first sentence, haven't I? Well, the guests on the show are none other than the current top guys on the Johnny's Entertainment mountaintop, Arashi（嵐）, just when they were starting out. Apparently, some hypnotist was playing around with them.
