Senior Prank worked!

In Illinois, a high school senior stole some stationery and envelopes from his school and sent out a formal letter to all senior parents telling them that there will be a "mandatory body cavity search" at prom for contraband. Needless to say, the letter was so well done that everyone's parents flipped out and have flooded the school with hundreds of outraged phone calls and emails! The senior who pulled off this work of genius has still not been identified! Too funny!
