I was carpooling with my friend Craig, he noticed that the "Check oil" light was on. He pulled into the gas station, got out of the car, opened the hood, checked the engine oil, closed the hood, then got back into the car. "Can we make a quick stop?" He asked. "Sure," I replied, "what did you need to do?" "I need to stop by the auto parts place to get a longer dipstick." "What do you need a longer one for?" I inquired. "Because the one I got isn't long enough to reach the oil!"
