Calvin and Hobbes by Bill Watterson for September 18, 1990
Dad: Here, maybe this will make more sense. I have eight pennies. I ask you for four more. Calvin: I say forget it. You're the one with a steady paycheck. Dad: Just give me the four pennies. Good. How much money do I have now? Calvin: Investments and all? Dad: No, just here on the table. Calvin: Eight cents. Dad: No, eight plus four is twelve. See? Count them up. Calvin: But those four are mine!
