Since Edward Ferrars has essentially become a Runaway FiancÚ, his mother simply plans for his intended, Miss Morton, to possibly marry his brother Robert instead. The CMoF comes from John Dashwood's incredulous reaction to Elinor wondering if Miss Morton gets a say in this.
Robert Ferrars and his toothpick case!
Who is taller — Harry Dashwood or William Middleton? The world must know!
Lucy Steele can hardly make up her mind on this capital point.
Thompson's acceptance speech at the Golden Globes, which she also won for Best Adapted Screenplay; rather than give a real speech, she reads to the audience what she imagines Jane Austen might have written in her diary about attending the award ceremony. The speech is viewable on the DVD.
When Elinor fails to coax Margaret out of hiding, Edward comes in and - guessing that Margaret is an avid reader - starts asking for maps to confirm wildly inaccurate "facts", each inaccuracy funnier than the last. It works in getting Margaret out of hiding to berate them.
When Willoughby disappears, Marianne throws a fit that Elinor tries to calm with a cup of tea. The scene quickly dissolves into three of the Dashwood women - Marianne (upset over her boyfriend's disappearance), the mother (upset that her daughters can't find happiness), and Margaret (upset that Edward's not coming to court Elinor) - storming off to separate parts of the house to slam doors and cry. Elinor calmly sits down on the stairwell and sips the tea.
Fanny's reaction to finding out who Lucy wants to marry. Most satisfying.
VIPER IN MY BOSOM!
Edward's interactions with Margaret, which endears him to Elinor:
Edward: She is heading an expedition to China shortly. I am to go as her servant but only on the understanding that I will be very badly treated. Elinor: What will your duties be? Edward: Sword-fighting, administering rum and swabbing. (later) Edward: What is swabbing, anyway...?
When he is first teaching Margaret how to sword-fight, he catches a glimpse of Elinor watching them from a window. Margaret takes advantage of his Distracted by the Sexy moment and "stabs" him in the gut, knocking him over.
Mr Palmer holding his howling baby son with a rather resigned look on his face while his wife fusses over the kid, and Brandon watching dubiously.
Honestly, any of the Palmer interactions— Hugh Laurie and Imelda Staunton play off each other perfectly.
