My cousin married a fellow from the UK and soon his father and my uncle became friends. The Englishman, Simon, had never owned a car but decide to buy one. He asked my uncle about maintenance so Uncle OC showed Simon how to check the oil and showed him where to drain it for an oil change. A few weeks later Simon announced he was planning to change the oil in his recently acquired used car on the coming Saturday. Uncle OC called Saturday afternoon to ask how it went and was told by Simon's wife that he was still at it after three hours. Uncle OC arrived at Simon's house and went into the backyard to find Simon loudly cursing while he was intently using an eyedropper to add new oil into the dipstick tube. He told Uncle OC that oil changes were a major pain and in the future he would have a garage do the work. After Uncle OC recovered from laughing he showed him the oil cap.
