When my sister was in High School their annual play for the Drama Club was "The Sound of Music" One of her friends played a nun in that musical. After it was over all the players kept their costumes and a few years later the friend decided to wear it again to a costume party - probably Hallowee'en. On the way to the party they stopped at a traffic light and a family of a woman and 3 children pulled up alongside. The woman told the children to wave to the nun and as they did so the friend of my isiter extended her middle finger in their direction. My sister tells it better than I.
