"Knock, knock," you say. "Who's there?" the huge feminine robot replies. "Boo," you answer. "Boo who?" she asks back in traditional format. "Dont cry," you begin the punchline, "it's just a joke." Surprisingly, she finds your awful joke hilarious. She starts with a giggle, but that turns into a full laugh which is soon an uproar. Soon she's laughing so hard that the chunk of earth holding you and your home's remains tumbles from her grip and twists a hundred feet down to the ground.
