Calvin and Hobbes by Bill Watterson for December 13, 1989
Calvin: Miserable miscreant! Question my integrity will you? Hobbes: I can't question it until I see some evidence of it! Clavin; Aaughh! I've been fighting! Hobbes: Only in the loosest sense of the word. Calvin: Santa, he made me! I didn't mean to fight! Hobbes: Yes he did! Yes he did! He started it! Calvin: I did not! Hobbes: Did too! Calvin: Did not! Hobbes: Did too. Calvin: Liar! Hobbes: Liar!
