An anonymous philisophical plagiarism

When I was doing a degree in philosophy we had to write an essay on transcendental deduction and space. Kant is pretty tough going and one of my friends was really struggling. She met a philosophy lecturer from America in a social situation and explained her plight. He emailed her an essay he had written about transcendental deduction and time, thinking it might help her. Seeing a way out and the deadline looming she just replaced the word "time" for "space" and handed it in. I'm not sure it made much sense but she got a D+.
