Calvin and Hobbes by Bill Watterson for April 03, 1991
Hobbes: You're the only person I know whose good side is prone to badness. Calvin: That's why he evaporated. He could only be perfectly good as an abstraction. In his human manifestation, he wanted to throttle me. He spectralized just in time! Hobbes: Fascinating. Calvin: Yes. Hobbes: Of course, now you have to do you homework yourself. Calvin: Actually, now that my good side is no longer a physical being, I find him that much easier to ignore.
