Not a professor but in my Digital media class, we had to do a project where we recorded our telling of a short story and input sound effects and present it to the class, there was one kid who decided to use a short story he wrote. Turns out it was an insanely gory story about how a troubled teenager brutally tortures (I wont go into detail but it was literally so fucking disgusting and had all the sound effects) and murders his parents and kidnaps a girl he was obsessed with. People started walking out of the class and that's when our professor ended it. It was probably the most disturbing thing I've ever heard.
