How Does Santa Go down the Chimney?

When Santa arrives at a childs house on Christmas Eve, does he go down the chimney feetfirst or headfirst? What if he gets stuck? What if theres no chimney? Maybe he slides under the door, as thin as a piece of paper? Or is it possible he pours himself through the tap? What happens once hes inside? Mac Barnetts iconic talent for earnest deadpan humour and Jon Klassens irresistibly funny art honour this timeless question with answers both ridiculous and plausible, mounting in hilarity as the night continues.
