Hehe one place I worked, we had assigned parking spots, and mine kept being taken, and I'd complain a lot to HR about it. Once, I'd gone to the junkyard and gotten a side mirror for my wife's car, and had it sitting on my table. I saw the HR chick walk past and said "HEY!" She came back to see what I wanted. I held that mirror (with all the cables and such) up and told her "Someone parked in my spot again, but I took care of it this time". The look on her face was precious.
