Be prepared to hear things that you’ve heard before

If only my students were as good at plagiarism as Peter Schickele . . .

But they’re not. (If one of them gave me a paper composed entirely of distinct, correctly cited and recognizable quotations – each of no more than a sentence or two – from a wide variety of historians, assembled into a coherent and well-argued essay that addressed the assignment, I would be sorely tempted to pass it. And/or distribute it to my colleagues.)
