The Butler, the Husband, the Wife and Her Mother

Fran's wealthy and obnoxious cousin comes to town, bragging about her great life. When she appears, Fran pretends that she owns the Sheffield's home (on her mother's impulse of course). To do that, Niles pretends to be Mr. Sheffield and Maxwell has to pretend to be Niles. Things only get more complicated when the Butler's Association comes to evaluate "Niles". In the end, everything is revealed, and Fran's cousin is impressed by the family.
