Calvin and Hobbes by Bill Watterson for March 07, 1988
Dad: Hey, Calvin! Guess what time it is! Calvin: Why? What time is it? Dad: It's a very special time! Calvin: Oh boy, oh boy! What time is it? Dad: Do you really want to know? Calvin: Yes, yes! Tell me! Tell me! Quick! Please! Yes! Dad: It's your bath time! Oh boy!! Calvin: You know how older people always write to Dear Abby, complaining that their kids never write, call or visit? Those letters really crack me up.
