Dorothy: There's no place like home.
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!
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.
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?!
Wicked Witch: I'll get you my pretty, and your little dog too!
Dorothy: Follow the yellow brick road.
Auntie 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 thought of you, and now... well, being a Christian woman, I can't say it!
Dorothy: Toto, I have a feeling we're not in Kansas anymore.
Answer: In all likelihood, probably not. Water is often depicted and represents purity, and cleansing. It flows smoothly, is beautiful, clear, and responsible for life on Earth. Everything the Wicked Witch is not. Where as the good Witch is pure and of a true heart. So it makes sense that something so evil and impure as the evil witch would be effected by the purest substance there is, yet not harm the good witch because she is good.
