-Tell me Harry, what exactly is a plastic duck for?
 -Oh, uh… Harry was surprised by that question. He knew Arthur Weasley was an avid Muggle enthusiast, Ron had told him that often enough in the past year, but he hadn't expected a question like that.
 -Well… when the kids take a bath, we give them a plastic duck to play with in the tub.
 -Ah, okay, thank you very much Harry! And Arthur said to himself that he had been right not to believe his colleague when he told him that a plastic duck could serve as a screwdriver.
