Calvin and Hobbes by Bill Watterson for December 24, 1987
Calvin: Psst! Are you awake? Hobbes: Of course. Calvin: I haven't heard Santa yet, have you? Do you think he's coming? Hobbes: It's only 11:00, we may be on the later route. Calvin: *gasp* Did you hear that? Hobbes: It's him! It's Santa! Shhh! He's saying something! Dad: Slppin' rippin' dang fang rotten zarg barg-a-ding dong! Mom: Quiet, dear! Calvin will hear you!
