--Publishers Weekly

[A] genial and witty picture book. . . Rather than answer the question outright, Mr. Barnett does what parents generally do--he dodges it--in this case by posing a series of childlike speculations: 'Does he cinch up his belt? Or shrink himself down to the size of a mouse?' In Mr. Klassen's pictures, Santa is comically deadpan through ever-more outlandish propositions.
