* The cook's continuous (and rather futile) insistence that the children can't come into the kitchen because ''she has it in writing!''
* "Pleased to meet you. I'm Oglington Fartworthy."
* From the sequel: Celia and Megsie have to work together to prevent Isabel from signing the farm over to the uncle without letting on that ''the DisappearedDad may be alive'' before proof is in hand. It's not the BavarianFireDrill that follows (with Celia going EekAMouse like crazy), it's Celia trying to instruct the Megsie's next move ''[[http://www.youtube.com/watch?v=dmeaDIqXIrU&t=10m12s while still screaming]]''.
* The following exchange in the first movie, between Selma Quickly and her friend.
--> '''Mrs. Quickly:''' "...What do you take me for, some common-" *cut off as she hears a knock at the door*
--> '''Friend:''' Tart?
--> '''Mrs. Quickly:''' [[ComicallyMissingThePoint No thanks, I'm bloated.]]
* This bit of GettingCrapPastTheRadar, when Mrs. Quickly meets with the Brown children after she thinks [[ItMakesSenseInContext their father just wanted to ravish her]].
--> I know what he wanted, and it wasn't marriage! No wonder there are so many of you.
* The children manage to keep their Great Aunt Adelaide from taking one of them by [[spoiler:passing off the scullery maid, Evangeline, as one of their siblings, so she could be raised and given an education and the actual siblings wouldn't be broken up]]. At the end of the movie, [[spoiler:Mr. Brown and Evangeline finally admit their love for each other and agree to marry]]. In the midst of the congratulations, Great Aunt Adelaide gives a horrified cry of [[spoiler:"Incest!"]] This then leads to Mr. Brown having to explain to the priest that no, [[spoiler:Evangeline is not actually his daughter.]]
* "Come on, Simon. Bowling practice!" [[ItMakesSenseInContext Said while Mr. Brow is holding a violin like a cricket bat and his son is preparing to throw a small cake.]]
* After continually startling Mr Brown by appearing behind him from out of nowhere ("I did knock") Nanny McPhee then appears in the kitchen while Ms Blatherwick is cooking. The cook turns to spot her...and instead of being startled, casually gets on with what she was doing.
