When I went to the automobile dealership to pick up my car, I was told the keys had been locked in it. I went to the service department and found a mechanic working feverishly to unlock the driver's side door.

As I watched from the passenger side, I instinctively tried the door handle and discovered that it was unlocked. "Hey," I said to the technician, "this side is open!"

He replied, "I know. I already did that side."
