At the last place I worked a colleague and I used to play pranks on each other. One night after everyone had gone home I unplugged his keyboard and mouse from the back of his Mac (dirty front-end developer) and the same to his nearest co-worker, then plugged his into his co-workers Mac and his co-workers into his Mac. I wasn't in the next day but apparently it took them about half an hour before they figured out what had happened.
