Who was the worst teacher you ever had, and why?

[Michelle]

A french teacher I had in Jr. High. Among other things he told an obese student that he should just buy a curtain to wear instead of a grad gown, told another student he had a face only a mother could love, and when I was moving to a new province asked if my parents could hurry the process along because he was sick of having me in his class. He told us he was going on vacation to Cuba, so he would be gone for a month. During this time, nude photos of him on a gay cruise showed up on his public Facebook page. He was never fired. I think it was because the school was in a very isolated, small area and they had trouble even getting subs, let alone replacing a permanent teacher.

BQ:
The best teacher I ever had was actually a student teacher who replaced the above teacher when he took a year off. She was the perfect mixture of being a friend and being an authority figure to her students. Everyone loved her, but also respected her. She was hilariously sarcastic and awkward, but very intelligent. I had her for history, which was a subject I hated, but I always looked forward to going because of her.
