Murray,I always suspect these are the same people who avidly watch the likes of Sally Jesse Rafael and Maury Povitch -- however they're spelled -- where the theme for the day is "My Brother Cheated on Me with His Sister-in-law" or some such. I don't know where they come from, but they probably have damned little to display in their lives.
Just think of those bumper stickers as a shouted warning: You Don't Want To Know Me.
