When I was in grad school, one of my classmates (attractive young coed) begged me to teach her how to change oil. Against my better judgement, there I was under the car...she in a skimpy top and me with oily hands. It was like something out of a sitcom. I'm sure you guys will believe that my ONLY interest was in working on an unfamiliar car, but my old lady was not impressed to say the least. Fortunately word got out that I was the 'go to' guy and I had a couple of other friends (male international students) over for a little car care clinic. They seemed amazed in the average American's ability to do such things. Wife just shook her head.
