Here is a funny story from book "The Art of Getting Even" by Gary Brodsky
"Once I had the privilege of driving a guy I hated to the airport. Since security check points are strictly regulated, I was certain that my prank wouldn't go unnoticed. While I was helping the guy unload his luggage from my car, I slipped a handful of 9mm bullets into his jacket pocket, along with a photo of Yassar Arafat. When he went through the metal detector, the bullets set off the alarm, and they checked his pockets. My prank worked better than I had planned, as the security people detained the guy for eight hours of intensive questioning."
What you think about it? Any comments are welcome ;)
