Calvin and Hobbes by Bill Watterson for December 10, 1989
Hobbes: Know what this is? Calvin: It's a polar bear blinking in a blizzard! Ha ha ha ha! Hobbes: Know what this is? Calvin: In snowed! Oh my gosh, look at it all! A creeping mountain of ice has crushed half the neighborhood! It's a glacier! Right in my own town! Everything north of here has been wiped off the face of the earth! This is great! Wow! Wooly mammoths! I've never seen those before! It's a new ice age! Hoorayy!! Sled city! One...lousy...half..inch! Hobbes: Look, the sun is coming out!
