He writes about not having read Anna Karenina in time for the first pop quiz and answering the question based upon the movie. A cardinal sin in a literature class. He writes with equal measures of glee and disbelief about his great good fortune that Nabokov didn't know the film and that, in the great writer's eternal optimism and belief that the human imagination can take what is on the page and run with it, he was not punished but rather hired as Nabokov's film-watcher.
I can't believe he thinks he got away with it. He was so obviously caught and this so literary a punishment.
