I had an art teacher who told us we had to draw models in specific ways, in such a way that everybody in class would get the same end result, I would follow along, get my piece done, then usually go over it. removing the eyes, adding joker slits to the mouths, putting the characters in weird cult-ish robes, etc
so the teacher kept pointing me out to the class as a bad example and telling me that what I was doing was not art (because it was different to everyone else's work)
then again, the same psychotic bitch spent an entire week ranting about how she's a rebellious artist due to the fact that her teacher in primary school told her not to mix colored paint with black paint, but she mixed black and yellow to make ugly green... which was apparently enough for her to make art a career choice and torment people with retarded teachings
