In high school, I drove a Ford Ranger. My best friend sold his Dodge Dakota to buy a Ranger after riding around with me. Mine was a 1992, his was a 1991. Back then, there were separate keys for the door locks and the ignition. He was joking around one day on the passenger side waiting for me to unlock the car, stuck his key in and unlocked it for himself. We were a bit surprised. The ignition key did not work, but after that discovery I found my truck packed full of all kinds of stuff when I'd go out for school in the morning (packing peanuts, toilet paper, etc.)
Similarly related - the youth pastor at our church was delivering a sermon and told a personal story about driving an old Honda ... said he had a strip of moulding on the passenger side that was always trying to peel off and flapping against the car while he drove down the highway. One day he came out of a home improvement store, headed to his car, noticed the strip of molding hanging down again (his tape never seemed to stick) ... he approached the car, grabbed the molding, yanked it off entirely and walked around to the driver's side. Only then he discovered his car was in the next row and he had just ripped the molding off of someone else's car.
