I had never seen this episode the first time around when it aired. Theodore Bikel plays Edith's longtime butcher who has a crush on her. He brings his fiancee over to the Bunkers for cake and coffee, a introduces the cranky German woman to everyone, also played by Jean Stapleton in a wig and glasses. When she interacts with Edith, there is split screen technique and a Patty Duke stunt double, and the gimmick of it all is fun. And Jean Stapleton played someone with a completely different character, energy and personality, opposite herself, in the role of Edith, so that was what made this episode memorable.
