Aunt Em: Elmira Gulch; Just because you own half the county doesn't mean you have the power to run the rest of us! For twenty-three years I've been dying to tell you what I've thought of you and....well....being a Christian woman I can't say it!
— Aunt Em's The Reason You Suck speech to Ms. Gulch.
Cowardly Lion: Come on, get up and fight, you shivering junkyard! [goes over to the Scarecrow] And put your hands up, you lopsided bag of hay!
Scarecrow: Now that's getting personal, Lion!
Tin Woodsman: ...yes, get up and teach him a lesson!
Scarecrow: Well, what's wrong with you teaching him?
Tin Woodsman: [stammering] Well, I-I hardly know him!
The Wizard: Step forward, Tin Man! You dare to come to me for a heart, do you? You clinking clanking clattering collection of caliginous junk! [to the Scarecrow] And your affronterage would ask for a brain! You billowing bale of bovine fodder!
The Cowardly Lion: All right, I'll go in there for Dorothy. Wicked Witch or no Wicked Witch, guards or no guards, I'll tear them apart. I may not come out alive, but I'm going in there. There's only one thing I want you fellows to do.
Tin Woodsman and Scarecrow: What's that?
The Cowardly Lion: Talk me out of it.
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: Yes, I guess you're right.
The Wicked Witch of the West: How about a little fire, Scarecrow?
Scarecrow: No! No! [as his arm gets lit on fire] Help! I'm burning! I'm burning!
(Dorothy grabs a bucket of water to extinguish the fire on Scarecrow's arm.)
The Wicked Witch of the West: Don't touch that water!
(Dorothy throws the water, extinguishing the flame on the Scarecrow's arm and splashing it upon the Wicked Witch's face. The Wicked Witch screeches in pain.)
The Wicked Witch of the West: 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? Oooooh, look out! Look out! [weakly] I'm going! Oooooh! Ooooooh!
(One of the Flying monkeys pokes at the steaming pile of robes and screeches.)
Winkie Soldier: She- She's dead! You've killed her.
Dorothy: I didn't mean to kill her. Really I didn't. It's just that he was on fire!
Winkie Soldier: Hail to Dorothy! The Wicked Witch is dead!
— The Wicked Witch's death scene from the 1939 movie.
The Wizard: You, my friend, are a victim of disorganized thinking. You are under the unfortunate impression that just because you run away you have no courage; you're confusing courage with wisdom.
—To the Cowardly Lion, after the Wicked Witch of the West was defeated
The Wizard: A heart is not judged by how much you love; but by how much you are loved by others.
— To the Tin Man, after the Wizard gives him his heart-shaped watch
The Wizard: I can't come back, I don't know how it works. Goodbye, Folks!
— After he took off on the hot air balloon without Dorothy.
The Wizard: Oh, oh, oh! (Clumsily tries to close the curtain.) Pay no attention to that man behind the curtain!
The Wizard: Child, you've caught me to the quick! I'm an old Kansas man myself, born and bred in the heart of the Western Wilderness.
Dorothy: Oh, Auntie Em! There's no place like home!
— Last line from the movie.
