Calvin and Hobbes by Bill Watterson for February 10, 1991
Calvin: While lying on my back to make an angel in the snow, I saw a greenish craft appear! A giant UFO! A strange unearthy hum it made! It hovered overhead! And aliens were moving 'round in view ports glowing red! I tried to run for cover, but a hook that they had low'r'd snagged me by my overcoat and hoisted me aboard! Even then, I tried to fight and though they numbered many, I poked them in their compound eyes and pulled on their antennae! It was no use! They dragged me to a platform, tied me up, and wired to my cranium a fiendish suction cup! They turned it on and current coursed across my cerebellum, coaxing from my brain tissue the things I wouldn't tell 'em! All the math I ever learned, the numbers and equations, were mechanic'ly removed in this brain-draining operation! My escape was an adventure. (I won't tell you what I did.) Suffice to say, I cannot add, so ask some other kid.
