"No you can't, sir. According to article ii section 8 paragraph of the magic school book, it is illegal to take away powers from students unless they put the attendance in grave danger. This includes actions such as burning witches alive, harvesting their souls, releasing toxic gas outside the (public) restroom, zombifying more than 20% of the school population, etc."

"I remember this, because last summer I had to write that entire book as punishment. Each day. Not fun. Besides, you and I both know it is just a matter of days before I get twice as ripped as I am today. As long as I don't harm someone beyond repair, I am as safe as a steel box with an iron lock. You can't touch me."
