Wizard of Oz, 1939

Glinda
Well, I'm a little muddled. The Munchkins called me because a new witch has just dropped a house on the Wicked Witch of the East.
And there's the house, and here you are, and that's all that's left of the Wicked Witch of the East.
And so, what the Munchkins want to know is - are you a good witch or a bad witch?

Dorothy:
But I've already told you, I'm not a witch at all. Witches are old and ugly. What was that?

Glinda:
The Munchkins. They're laughing because I am a witch. I'm Glinda, the Witch of the North.

Dorothy:
You are! I beg your pardon! But I've never heard of a beautiful witch before.

Glinda:
Only bad witches are ugly.
