Oh man, that would have to be "Steve". It was a coop that later turned into a job. We were working on a medical product with an embedded 68K system in it, with a Mac front end. He was a hardware engineer who thought he sort of knew everything. He had a junior engineer working for him that he literally would ask to _count_the_resistors_ in the cabinets. This guy was working on code for another small device that applied test signals to the larger device. After everyone went home, he'd go onto the guy's computer and "review" the code, changing stuff without telling him, in a large 6800 assembly program. I was working on the front end software on the Mac, which was in C. One day "Steve" asked me to print out the code so he could "review" it. I dutifully printed out all 75,000 lines of it, walked into his office, slapped it on his desk and said, "Go ahead." He never bothered me again. You can imagine how well the hardware worked and how fast it got done, right?
