The CS instructor who was (maybe an adjunct?) who no matter what homework we turned in gave us randomly different grades. We actually all handed in the same hw one time to see what would happen (only changing variable names and such), and confirmed it. Also, he used to call me J-Lo when I'd raise my hand to answer questions. (I was fit and am Latina) The second time he did it, I sternly corrected him in front of the whole class. He stopped after that. And yes he was gone from the school soon after!
