I saw these two at the Pavarotti and Friends open air concert in Modena in 2002- I think this is it!

This is fantastic prank and I think it is absolutely hilarious. Good for them for having a bit of fun and doing it in such clever fashion. I am one proud LHS alumna and hopefully the administration has more important things to do that try and use any and all methods to find out the culprit. Nobody got hurt and no school property (unlike damage done by grafiti)was harmed. Let the kids have some fun!
