This episode makes use of footage from the 1960 episode "David Hires a Secretary." In that episode, June Blair Nelson played one-time character "Cathy Carson," who came to work as a temporary at the law firm. In the new episode, it is implied that we are actually seeing David's wife June in the flashback footage as the Nelson's look back on her work at the office.
The use of the old scenes is a clever way to save on costs and work. This episode is now commonly available on DVD for viewing, affording fans a look at one of June's earliest appearances on the series. June is absolutely delightful and always presents some of the best and most memorable work of the very early '60s seasons of O & H. Her chemistry with David mirrors that of Ozzie and Harriet themselves: A loving couple who enjoy to kid each other at times, and we become enamored of them.
