Couldn't the girls just interrupt and speak up? Screw etiquette, if you want attention, demand it. I know thats how Makoto caught my attention when she did these types of shows. I think Yaguchi got where she is now hosting several shows just by being so vocal on her own. I love Ai (so much its even creeping me out) but like that other guy said, she and the rest blew it.
Anyways, Johnson was there and you know Ishibashi wouldn't pass up on the chance to tease her. Hell, you can see how fast he went from MM to poking her. Get him in a crowded room.. throw in Yasuda, Nakazawa, or Kaori and you know where Ishibashi is going.
