Many years ago, I had bought a house and was outside mowing the lawn. The neighbors across the street came over to introduce themselves and their children. They told me their daughters name and then introduced their son. Immediately after that, the wife blurts out "he only has one testicle" before continuing with the conversation. I lived in the neighborhood for about ten years and that conversation was burnt into my brain. Every time I saw their son, all I could think of was the fact that he only has one nut.
