GOOD! I did similar things in school. "You can't do this"
"Watch me!"
I also did the same thing in University, where I wrote a paper about how video games were Art. The tutor, a post-modernist example of artiste, failed the paper. I resubmitted it to the course coordinator, unchanged. He gave it the highest possible grade.
I was working professionally, at the time, for a video game publication - and had published many editorials on the topic, and referenced my own writing in my own paper. He liked that. The tutor did not. :P
