Charles Carson: [picks up phone] Hello. This is Mr. Carson the butler of Downton Abbey. To whom am I speaking?
Charles Carson: I'm not shouting! Who are you?
Charles Carson: Ah, Mrs. Gaunt.
Operator: And what number do you want?
Charles Carson: No, I don't want to place a call.
Operator: What were you doing, then?

Violet, Dowager Countess of Grantham: What more do you need?
Lady Mary Crawley: I hope you know that really smart people sleep in separate rooms.
Robert Crawley, Earl of Grantham: I always keep the dressing room bed made up so I at least pretend we sleep in separate rooms. Isn't that enough?

Robert Crawley, Earl of Grantham: Pregnant?
Cora, Countess of Grantham: You needn't be quite so shocked.
Mrs. Bird: [when Matthew asks her to help in Lord Grantham's kitchen as cook while Mrs. Patmore is away getting eye surgery] I'm surprised Lord Grantham knows that I exist, sir.
Violet, Dowager Countess of Grantham: [to Mrs. Crawley when they realize Mary will not take Matthew despite the fact that he remains the heir to the title and estate] Your quarrel is with my daughter, Rosamund, and not with me. So put that in your pipe and smoke it.
