Calvin and Hobbes by Bill Watterson for January 15, 1990
Mom: Calvin! What are you doing outside? Didn't I just send you to clean your room two minutes ago?! Calvin: No. Mom: I did too! Now get back upstairs. I'm losing my patience for this game! Calvin: She must've found my duplicate! C'mon Hobbes, we'd better hurry before he gets us in more trouble! Number three, hi! I'm number two! Charmed.
