Reminds me of one of my neighbors long ago - he was an older guy and very mechanically UN-inclined-but at the time we had no idea just how clueless he was. He had noted that his car's temperature guage was running a bit high, and had asked us what to do - we said, check the coolant level and if it seems low, add some water to it. We didn't expect that he would interpret the little oil can symbol with the drop of oil coming out its tip to be a water can symbol (his claim) - he filled that engine up until water was up to the top. Later that afternoon he went to start the engine.. OF course, THEN he came over to get us to investigate why the engine wouldn't start.
