Calvin and Hobbes by Bill Watterson for February 10, 1990
Calvin: The inside of my head was exploding with fireworks. Fortunately, my last thought turned out the lights when it left. When I came to, the pieces all fit together. Jack and Joe's lives were defined by integers. Obviously, they were part of a "numbers" racket! Back in the office, I pulled the files on all the numbers big enough to keep Susie quiet and want me out of the picture. The answer hit me like a .44 slug. It had to be the number they called "Mr. Billion." Calvin: Case closed! Miss Wormwood: Time's up. Bring your papers forward. Susie Derkins: What did you get, Calvin? I think the answer's 15.
