Comedy Sitcom

Elizabeth and Alvin are an ordinary suburban couple, but inevitably get into predicaments. In the end, Alvin, in variable degrees of frustration, would say, "I shall leave you at this point, Elizabeth" and would walk out of sight. The announcer would say, "Elizabeth, aren't you ashamed?" She would slowly nod, but then, with a slightly devilish grin, would vigorously shake her head to indicate she wasn't.
