This reminds me of an incident which occurred when I worked in a physician's office. The office manager and I were the only two in the office with the least bit of mechanical ability. We had to put in an under cabinet light. I noticed that she had broken out in a sweat and stopped the installation process leaving me holding the light. When I asked her what the problem was, she announced in her most unladylike voice what was heard by everyone in the whole Pediatric Office, "this screwin' upside down is hard work". We were still teasing her about it years later.
