I got secret revenge once. It was in high school. Some band boy TP'd my house, so I got him back. It went back and forth for several months. Then he took it a step up and egged my car. LAST STRAW!!!! SOOOO, a couple months after that the band and tall flags (that's me) went on a trip to San Diego. He was there too (so he knew I was there). My best friend picked up dog crap from her lawn, bologna, and eggs and flung it all over his car. He had no idea it was me and stopped TPing my house. Sweet, sweet revenge!!!
