Get a load a this!(slant 6 with a hole)

When i was about 18 I was working in a corner service station, did oil changes and tire repairs mostly in those days. One Saturday morning a woman came in with a Duster, /6 car, and asked if I had time to change the oil for her. Drove the car in, oil light was on steady, had the typical /6 rattle, set it up on the hoist and removed the drain plug. Not a damn drop of oil came out! Pulled the filter, a small amount of oil remained in it, and it was quite heavy. I went to the waiting area and told her that there was no oil in her engine. Her reply? "Oh, I thought it was due for an oil change!" I went back into the shop shaking my head at the thought of this engine running without oil, put a new filter on, gave it a thorough grease job, let it down and filled the crankcase with fresh oil. Touched the key and it fired right up, oil light was now off and it ran just fine. The woman paid for the service, I backed her car out and she drove off. Damndest thing I had seen at that point in my life, I still wonder how much longer that car ran, never saw the woman or the car again.
