Now this is a lot more Calvin and Hobbes-esque than some strips people have tried so hard to find evidence of plagiarism for. Calvin would usually make something nonsensical or simple and use elaborate art jargon to justify how ground-breaking it was.
Incidentally, I was just re-reading this one C&H story arc where Calvin turns a melting snowman into a modern-art masterpiece, thus beginning his career of abstract snow-art.
OK. pants it. I lied. It's drum and bass. What you gonna do?
I think the difference is that Calvin was using high-falutin' art terms to justify making some really weird crap that would get any other kid sent to therapy and Millie is a girl.
That which does not kill me, cripples me for life.
