Don't encourage them
Thank God someone could make the right decision by not promoting silly acts. ("Don't want their MTV -- School won't help cable network recreate 2003 graduation prank" (http://www.mccookgazette.com/story/1089068.html))
It's a funny high school prank, but impressionable youth's don't need to be encouraged all over the nation. Which MTV's cool, "it's all good" attitude would defend their reason of why this is no big deal.
How about the videos with kids pounding tacks into their head. That's greaaat.
All right Nebraska! Ya think the rest of the U.S. could understand this?
I'd hope the school could resist even if there was money involved.
