Professor Henry Higgins: She's so deliciously low. So horribly dirty.

Professor Henry Higgins: The French don't care what they do actually, as long as they pronounce it properly.

Professor Henry Higgins: The question is not whether I've treated you rudely but whether you've ever heard me treat anyone else better.

Professor Henry Higgins: There even are places where English completely disappears; in America they haven't used it for years.

Professor Henry Higgins: Why can't a woman be more like a man?

Professor Henry Higgins: Would I run off and never tell me where I'm going?

Professor Henry Higgins: You impudent hussy!

Professor Henry Higgins: You might marry, you know. You see, Eliza, all men are not confirmed old bachelors like myself and the Colonel. Most men are the marrying sort, poor devils. And you're not bad-looking; you're really quite a pleasure to look at sometimes. Not now, of course, when you've been crying, you look like the very devil; but when you're all right, and quite yourself, you're what I would call... attractive.

Professor Henry Higgins: You see, the great secret, Eliza, is not a question of good manners or bad manners, or any particular sort of manners, but having the same manner for all human souls. The question is not whether I treat you rudely, but whether you've ever heard me treat anyone else better.
Eliza Doolittle: I don't care how you treat me. I don't mind your swearing at me. I shouldn't mind a black eye; I've had one before this. But I won't be passed over!
Professor Henry Higgins: Well then, get out of my way, for I won't stop for you. You talk about me as though I were a motor bus.
Eliza Doolittle: So you are a motor bus! All bounce and go, and no consideration for anybody. But I can get along without you. Don't you think I can't!
Professor Henry Higgins: I know you can. I told you you could.
[pause]
Professor Henry Higgins: [quietly] You've never wondered, I suppose, whether... whether I could get along without you.
Eliza Doolittle: Well, you have my voice on your phonograph. When you feel lonesome without me you can turn it on. It has no feelings to hurt.
Professor Henry Higgins: I... I can't turn your soul on.
Eliza Doolittle: Ooh, you are a *devil*. You can twist the heart in a girl the same way some fellows twist her arms to hurt her!

Cockney: We've got a bloomin' heiress in our midst. Will you be needing a butler, Eliza?
Eliza Doolittle: Well you won't do.
