Bucky Fuller story,
My wife grew up attending a UU congregation on Long Island. Fuller came to speek, and at the time my wife was like 10 YO. He went on and on about saving energy, and saving gas (era of the 1973 gas crisis) Mary raises her hand, and being a young girl, he calls on her, and she points out the window and asks "then why are you driving a Rolls Royce?"
