Diving Lucy 121 years old

The biggest English comedy hit of the year. The scene is laid on an English estate at the edge of a pond. A couple of laborers discover, protruding from the water a pair of female legs. They hasten to the rescue, secure a bench and a long plank so as to get out over the water to the point where the legs are sticking up. Just as they complete their preparations a policeman runs up and insists on going out to the rescue of the female in distress.
