It's time for . . . plagiarism!
I asked my students to do a creative piece, and one of them did a rewrite of a text I happen to know quite well without acknowledging the source. Given, what this student turned in to me is only a draft, but it's still a formal assignment, insofar as it was turned it in to me with the expectation of receiving credit.
Oh, why do they do these things when it's so easy to avoid doing them?
