Calvin and Hobbes by Bill Watterson for December 22, 1985
Calvin: There! Our fortress is completely indestructible! HObbes: "Sunny and warmer today, high in the uppper thirties..." Calvin: Our snow fort is impenetrable! At the slightest provocation, well let loose a merciless barrage of stinging ice!! None dare attack us! We rule all!! Together, a veritable fist of defiance, we stand immune to any onslaught! We are invincible!! We..uh..umm..
When your fort is only 2 feet high, you shouldn’t get on a soapbox to make a declaration of invincibility.
