In a dark, dark wood there is a dark, dark house.
And in the dark, dark house there is a dark, dark hallway.
And in the dark, dark hallway there are some dark, dark stairs.
And down the dark, dark stairs there is a dark, dark room.
And in the dark, dark room there is a dark, dark cupboard.
And in the dark, dark cupboard there is a dark, dark box.
And in the dark, dark box there is a big mouse!
