Calvin and Hobbes by Bill Watterson for March 27, 1990
Mom: Look at you! How could anyone get so dirty at school? Calvin: I got this dirty just trying to walk in the front door! Ol' catapult butt was lying in wait for me. Mom: Well, it doesn't matter. You'd better get in the tub now anyway. Calvin: A bath?! But it's the middle of the afternoon! Mom: Yes, but I have to get in the shower before your dad gets home, so he can take one. Calvin: Why all the baths? Is there some epidemic going around? Mom: I told you this morning we're going out tonight. Rosalyn will be here at 6:00. Calvin: AUGHHHH!
Yes, Calvin. There IS an epidemic. Me!
