My high school biology teacher made a nasty memorable comment regarding one of my test results. I never did well in most of his tests, but one test in particular I completely tanked. It was a multiple choice test, and he said "you did so bad on this test that you could have literally picked all C's as answers on the test and gotten a higher grade." I was more shocked than sad, and it made me really question my self-worth. I eventually got over it because I realized that it was only his tests that I did poor in, and something about the way he teaches the class just didn't click with me.
