The Nanny (what else?)
1) Strange Bedfellows
Fran gets drunk and many interesting things happen between her, Mistah Sheffield, Niles, and CC. This is definitely my favorite episode.
2) Finale (both parts)
The twins are born, a certain butler and business partner get married, etc. There's an amazingly heartbreaking montage to The Way We Were at the end. I bawled.
3) Close Shave
This tells you all you need to know.
4) Where's the Pearls?
Elizabeth Taylor trusts Fran to take her pearls somewhere, but an insane taxi driver causes Fran to hit her head and develop amnesia. I love Fran's attempts to remember what her life was like, and the not-so-minor details she gets wrong.
5) The Whine Cellar
Fran and CC are trapped in the wine cellar together. Again, enough said.
6) The Nanny Napper
Fran inadvertently "kidnaps" a foreign woman's baby boy while riding the subway, and tries to take care of him, find out where to take him, and face kidnapping charges.
7) What the Butler Sang
Fran's sister Nadine comes to stay at the house and a sibling rivalry develops in which they act more like children than full-grown women.
8) Schlepped Away
While trying to escape snowy New York City for a vacation in the Caribbean, a snowstorm forces the Sheffields to stay at Fran's parent's apartment.
9) Here Comes the Brood
CC attempts (and fails miserably) to bond with the children by taking them to the zoo while Fran is attending her cousin's wedding as a bridesmaid. Contains humorous glimpses into Fran's family's utter lack of class and death threats by Fran to CC.
10) Ship of Fran's
Shot on location, this episode features the Sheffields' and Fran's Caribbean cruises which, so conveniently for Mistah Sheffield, happen to be at the same time on the same ship. Fran is looking for "the man of her dreams," but he's not all he's cracked up to be.
