The award-winning duo Mac Barnett and Jon Klassen compose an enjoyable, humorous story that provides possible answers to the most crucial question of Christmas: How does Santa Claus come down the chimney?

When Santa Claus arrives at a child's house on Christmas Eve, does he come down the chimney headfirst or feet first? And what if he gets stuck? What happens if there is no chimney in the house? Does he slide under the door like thin paper? Or is it possible for him to squeeze through the pipes and come out of the faucet? What happens when he manages to get inside the house?

Mac Barnett's iconic writing talent and Jon Klassen's irresistibly funny illustrations honor this timeless question with answers that are both funny and believable, enjoyed equally by young and adult readers.
