re: What's the dumbest thing a teacher's ever 'taught' you?

I once had a teacher get mad at me and three of my friends for making fun of this band nerd, and never paying attention in her class. She kept us after class one day and yelled at us, "you think you're smart, but you're not as smart as you think you are!"

The joke's on her, one of us has a doctorate, two of us have masters, and the last is a chemical engineer. I think she was just mad that we were as smart as we thought we were and didn't need to pay attention to her shitty lecture.
