^ the video you talked about is real... it was actually talked about in the news when the video first surfaced... the 3 kids were all sentenced to jail... although can't remember for how long...
-EDIT-
Just watched this fish video and have to say since the birth of the internet people seem to be getting weirder, and weirder or maybe it could be that every wacko now has internet access so they can all post up their un-usual behaviors... although with that all being said and done, the Japanese do have some very very un-usual kinky habits...
