The Party's Over The Nanny : Season 3 Episode 8

Mr. Sheffield and C.C. are going to Boston for the weekend, but what originally started as a romantic getaway plan for C.C. turned into family weekend thanks to Niles. Fran, Maggie and Niles have the house to themselves, and Fran decides to throw a singles party at the house to fish an eligible bachelor. But the party is over when an undercovered cop shows up and arrests Fran for not having the required licenses. After spending the night in jail, Fran returns home and Mr. Sheffield almost fires her, if it wasn't for Maggie stepping in and taking the responsibility for the mess. Fran goes to court, but Mr. Sheffield shows up in the last minute to help her from her senile lawyer, Uncle Mannie.
