Say, "You'll have to make me!"
From Create Your Own Story
Uncle Vernon shrugs and drags you into the boat. A dirty wet hunchback with crooked teeth leads you and the Dursleys into the stormy sea. He acts as if this were a summer fishing trip, and when a wave nearly topples over the boat, he whistles a tune. Uncle Vernon looks like he is about to puke, but luckily you make it to the island.
