Read it through once

“Why, whoever rubs the lamp or the ring. They belong to whoever rubs the lamp or the ring, and they’ve got to do whatever he says. If he tells them to build a palace forty miles long out of di’monds, and fill it full of chewing-gum, or whatever you want, and fetch an emperor’s daughter from China for you to marry, they’ve got to do it—and they’ve got to do it before sun-up next morning, too. And more: they’ve got to waltz that palace around over the country wherever you want it, you understand.”
