This strip was originally published in the newspapers on May 31, 1987.
Calvin finds himself no longer in the third dimension. He's only 2D. He's thin as a sheet of paper. His feet have no surface area. Only by waving his body along the ground can he generate enough friction to move. But having width but no thickness leaves him vulnerable to gusts of wind. To avoid drafts, he pulls himself into a tube to roll across the floor. Someone is coming, so he turns sideways to hide. As thin as he is, he's nearly an invisible vertical line. Dad is lying under the kitchen sink, trying to fix something. Calvin asks if he knows why he couldn't see him all morning. Calvin explains he was two dimensional. Dad mutters that he bets Calvin can't do it all afternoon also.
