Who does Dorothy's house kill in The Wizard of Oz?

The answer is: Wicked Witch of the East. Not only does Dorothy's house fall on and kill the Wicked Witch of the East, she even steals the witch's ruby slippers (with a little help from the good witch Glinda, of course). Bit rude if you ask me.Also, are bad witches only allowed to be named after cardinal directions? They must really love cartography.Source
