This episode was the first to air featuring Ethyl Phillips, though in fact the character's first appearance chronologically appears to be in "Employee of the Month." In that episode, Ethyl arrives for a visit prior to permanently joining the household.
This episode marked Tom Trbovich'sDinosaurs directoral debut. Trbovich would go on to direct 25 of the show's 65 episodes (more than any other director on the series).
