I'd imagine that the problem with the video being hosted is that it would probably require an "R" rating if it were shown theatrically.
The biggest shock to me, however, was that one of the kids was named "Jemimah".

By the way, I started watching this with my two ten year old boys, thinking it would be some harmless, fun video. They screamed when the first kids got blown up and ran out of the room absolutely petrified and wanting to vomit. Are you proud of that? Morons.
