Calvin and Hobbes by Bill Watterson for December 03, 1988
Dad: Hello? Calvin: Hi, Dad! It's me, Calvin. Will you tell me a story? Dad: Calvin, I'm at work! I don't have time to tell you a story now! I'm very busy! Get off the phone. I'm expecting important calls. Calvin: Ok, Dad. I'll just stay here quietly growing up at an unbelievable rate, never spending much special time with my own dad, who's always working. Dad: Right, right. This is the story of the hydraulic pump (fig. 1), the wheel shaft flange (fig. 2), and the evil patent infringement. Calvin: I want a good story.
