Calvin and Hobbes by Bill Watterson for March 01, 1987
Calvin: Drinking water. Oh no! What have a done?!? The human body is 80% water. Little did Calvin realize how critical it is to maintain that! Now it's too late! By drinking that extra glass of water, Calvin has upset that precious balance! He is now 90% water! Everything solid in Calvin's body begins to dissolve! He is becoming a liquid. His only hope is somehow to get to an icebox and freeze himself solid until he can get proper medical attention! Unfortunately, as a liquid, Calvin can only run downhill! Can he make it? Can he make it?? I don't think I'm gonna make it. Mom: There's a gas station up ahead. Just hold on. Dad: Didn't I tell you not to drink so much before we left??
