Personality
Melanie is feminist, and it is shown numerous times that she favours girls over boys. When she split the school in two, she decorated the girls side with art, sculptures, and fountains. She believes girls should have the best education experience possible. On the other hand, on the boys side, she did not decorate it and let it get dirty and look like a gang scene in a ghetto neighbourhood, with broken equipment. Melanie took over as the math teacher for the girls, however she did not teach math, she just taught about "how numbers make you feel", and "what does a plus sign smell like", obviously not real math subjects. After Principal Skinner's sexist comment that boys were better at math than girls, she took advantage of this. She hired a math teacher to teach 7th grade math to the 4th grade boys, while teaching basically nothing to the girls. Melanie told Chalmers that calling her by her first name was harrasment, a false claim. Then, she made out with him later. She was then replaced by Skinner as principal for an unknown reason.
