'Zachary's height is exactly the height of an average boy for his average age. Zachary's hair lies exactly the way of an average boy's on an average day. And when he dreams at night, Zachary dreams the most average dreams. Because Zachary Briddling... is awfully middling. And it makes him so grumpy!' Zachary wants to be different. So he thinks of all the other places out there-filled with giants, and miniatures, and hairy things, and flying things-places where he should not be middling at all. And so he sets out ... to stand out. The Grumpiest Boy in the World is a playful escapade of the imagination celebrating ordinariness and extraordinariness-and the grumpiness that can come from thinking we have too much of one, or not enough of the other.
