It's cool that it got noticed on the news, but I think the reporter guy totally knew what the video was about, despite the fact that he called the stop-motion video the "making of" thing, he just danced around the issue since he said it was #1 in Japan for a while, but he didn't say WHERE it was #1. Not entirely sure what he was afraid of, but w/e.
And yeah Youtube, /jp/ reactions are hilarious.
