Calvin and Hobbes by Bill Watterson for October 21, 1989
Calvin: I can't sleep, Hobbes. I've been thinking. Hobbes: What about? Calvin: Well, suppose there's no afterlife. That would mean this life is all you get. And that would mean I'm sitting here in bed as precious moments of my all-too-short life disappear forever. Mom: Honey, wake up. Di you hear the television on?
