Back in the 80's a bunch of us went to camp for a work weekend. I invited a coworker to ride along, just to get away for the weekend. We had a camp cook at that time that enjoyed stirring things up. He'd always try to get under someone's skin. I gave my buddy a little heads-up about "Diffy" on the drive to camp. Morning after the 1st night Diffy wasn't to happy. I found later out on the ride home my buddy put a few toothpicks in Diffy sleeping bag before he crawled in knowing he'd never get blamed for it.
