The nastiest and meanest thing I've done was back in May 2011, shortly after the 4/27 tornado that demolished Tuscaloosa, Alabama. I was working as a mechanic at a dealership, and had about $25,000 worth of tools, and toolboxes that cost around $10,000. I always had a 2 use rule with my tools when someone needed to borrow one of my tools, and that would give them ample opportunity to contact the tool distributor, and get the tools that they need. This one kid kept abusing my policy, and kept on going inside my toolbox grabbing my tools. I was off one weekend, and when I returned to work Monday morning as I was unlocking my tooldboxes, I noticed one of the top lid pins was pulled out about a quarter inch. I walked inside the office, and spoke with the service advisor who worked that weekend, and asked her who fucked with my toolbox, and the service advisor explained that they were busy, and she didn't pay close attention.
Moments later, the technician who worked along side me, told me to get inside the PDI(Pre Delivery Inspection) and go for a ride, and he had information to tell me. As we were test driving the vehicle before placing the vehicle on the lot to be sold, the tech told me it was Will who broke inside my toolbox, and had my toolbox open all day that Saturday, and he told Will to leave my box and tools alone. I told the tech I have a surprise for him.
Later that afternoon, Will had taken his lunch, and parked his vehicle outside his stall with the windows rolled down. I waited 5 minutes to give him time to settle down in the break room, and I proceeded to the parts department, and cut off a 6 foot length of ground wire. Went to my toolbox, grabbed a pair of wire strippers, ratchet, socket, and a pair of pliers. Went to Will's vehicle, pulled the hood release, and pulled off one of the spark plug caps. Then I proceeded to strip one end of the ground wire, and wrapped it around the spark plug, and fed the wire thru the firewall, and hid the wire under the carpet. Then I went to loosen one of the bolts to his seat, and stripped the other end of the ground wire, wrapped the wire around the bolt, and torqued the bolt back to the seat. Basically, I made a homemade electric chair.
At the end of the day as he was about to leave for the day, everyone stopped what they were doing, and said goodbye to Will, and as he got inside his vehicle, and turned the key in the ignition, he got the shock of his life on numerous occaisions. Everyone was laughing, and then he opened the hood, and saw my work. He told me I was wrong for what I did, and I told him to leave my tools alone, and no one told him to break inside my toolbox without my permission. Needless to say, he left my toolbox alone from that point forward as I told him I have more tricks up my sleeve if he continues to get my tools out of my toolbox.
