Calvin and Hobbes by Bill Watterson for March 23, 1986
Hobbes: How come we play war and not peace? Calvin: Too few role models. I'll be the fearless American defender of liberty and democracy. And you can be the loathsome godless communist oppressor. We're at war, so if you get hit with a dart, you're dead and the other side wins, ok? Hobbes: Gotcha. Calvin: Go! Kind of a stupid game, isn't it.
