Green Acres (1965)

S4E22 Oh, Promise Me

Upon reviewing their marriage license, Oliver and Lisa discover they are not actually married; they had been issued a dental practice license by mistake. Unwilling to stay in the same house as a single dentist, "Dr. Gronyitz" decides to stay with the Monroe brothers until they can get married properly. Their church wedding proceeds relatively well, especially given that Hank Kimball serves as the best man and Ralph Monroe takes on the role of maid of honor.
