Calvin and Hobbes by Bill Watterson for May 31, 1987
Dad: "Before beginning any home-plumbing repair, make sure you possess the proper tools for the job." "Check the following list of handy expletivies, and see that you know how to use them." Calvin: Calvin wakes up one morning to find he no longer exists in the third demension! He is 2-D! Thinner than a sheet of paper, Calvin has no surface area on the bottom of his feet! He is immobile! Only by "waving" his body can Calvin create enough friction with the ground to move! Having width but no thickness, Calvin is vulnerable to the slightest gust of wind! To avoid drafts, he twists himself into a tube, and rolls across the floor! Someone is coming! Calvin quickly stands up straight. Turning perfectly sideways, he is a nearly invisible vertical line! No one will notice! Hey Dad, know why you didn't see me all morning?? I was two-dimensional! Dad: Hmmm, I'll bet you can't do it all afternoon, too... Mom: Dear!
