DIscussions like this always remind of a bit from the Rodney Dangerfield movie "Back To School" . . . 

Dangerfield plays a self-made billionaire named Thorton Melon who never finished high school. Worried about how his son will do at college, Melon "arranges" (through the generous application of his boundless wealth) to attend the same college as a freshman. But - of course - Melon isn't actually interested in doing any schoolwork. So when his English lit teacher assigns an essay on the meaning behind "Slaughterhouse Five," Melon hires Kurt Vonnegut to write the essay. 

[The author actually has a walk-in part in which he's seen knocking on the dorm condo* door.]

To his vast surprise, when Melon gets the assignment back, he's gotten a very low grade (a "D" IIRC). When Melon complains to the professor, he's told, "You totally misunderstood the work." The silent look of bafflement Melon gives in response to this is classic Dangerfield.

*I call it the "dorm condo" because - in another display of wealth - Melon has persuaded the college to allow him to knock down the walls between three separate dorm residences and combine them into a single palatial bachelor pad.
