The Wizard of Oz (1939)

Dorothy: How can you talk if you haven't got a brain?
Scarecrow: I don't know. But some people without brains do an awful lot of talking, don't they?

Dorothy: There's no place like home.

Lion: [crying.] Look at the circles under my eyes, I haven't slept in weeks.
Tin Man: Well, why don't you count sheep?
Lion: Oh it's no use, I'm afraid of them.

Scarecrow: The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side. I've got a brain!

Dorothy: Follow the yellow brick road.

Wicked Witch: Ohhh... You cursed brat! Look what you've DONE! I'm melting! Melting! Oh... What a world, what a world! Who would have thought a good little girl like you could destroy my beautiful wickedness?!

Dorothy: Toto, I have a feeling we're not in Kansas anymore.

Wicked Witch: I'll get you my pretty, and your little dog too!
