I had a supervisor who was anal about having a chair that rolled smoothly across the floor. He had several computers lined up on adjacent tables and like to just scoot from one to the other. We decided to mess with him, so we took a file and filed little flat spots on the wheels of his chair. He about went bonkers trying to figure out WTF was going on. We kept filing a little more off the wheels. Finally, one of my cohorts took a grinding wheel to one of the wheels on his chair. To this day that living brain donor thinks his wheel on his chair sprung a leak and went flat.
And he was the boss!
