Well-meaning and optimistic, but naïve, clueless and spectacularly incompetent, Frank would find situations spiraling hilariously out of control. His long-suffering wife Betty can only stand by and watch as he is catapulted into "a bit of trouble" by the simplest task - a window cleaning job, a driving test, DIY or an RAF reunion.
