Calvin and Hobbes by Bill Watterson for March 16, 1990
Dad: How's your math coming? Calvin: I don't do math any more. I decided I'm more of a "visual" person. Dad: Good. Visualize being the only 45-year-old in first grade. Hobbes: Visualizing a few sums now, eh? Calvin: Actually, I'm visualizing you in traction. Help me do these, ok?
