A friend of mine brought his family to Disney World. He parked his minivan and walked his family to the front gate.  Having no interest in kids' plays, he returned to his car for a rest. A car parked not too far from his own was identical in brand and color. Most interesting thing was that his car key even opened the door. He got in and had a long nap. He reached for his drink and it was not there. Then found the contents in this car were not his either. Tried the ignition key and found not working. "Gosh, it is not my car!"

It was good he was not caught for break-in.
