Dorothy Gale's house

Dorothy's (AUDIO: The Settling) house (PROSE: Normality, Dead Romance, Mad Dogs and Englishmen) was a house in The Wizard of Oz which was taken from Kansas to the Land of Oz by tornado, (PROSE: Normality, Dead Romance) where it landed on a witch, prompting celebration. (PROSE: Mad Dogs and Englishmen)

This event was recalled by the Eleventh Doctor upon encountering the eye of the storm, (GAME: The Eternity Clock) as well as Clara Oswald, who couldn't understand where the phrase "safe as houses" came from when houses could, among other things, be taken to Oz by tornadoes. (PROSE: Normality)
