Who's got a good one? I'll share one of my favorites. Working for a grain elevator/fertilizer repair company our work used to take us on the road all the time. Different crews would get together to do the job, most often crews from different provinces would be put together. One guy thought it would be funny to put a ladies thong in my suitcase. He didn't know that I did my own laundry and found his surprise. The following week I acted like nothing happened and had his roommate plant them in his bag the morning we went home. I got a call from his angry girlfriend asking if this was the case. I convinced her to go along with it quickly and to keep sounding angry while I told her the story and asked her to go along with it. She did and the poor guy suffered. She let the gag run along time and was really good too! She eventually let him in on it and he let me have it on the phone and you could hear his girlfriend in the background telling him to,"Man up and deal, you started it!" Good times, good times!!
