When I was in High School we had a teacher fired for taking photos of kids changing after gym. But not the principal who used to watch us shower and point out that we hadn’t rinsed our private parts properly… :/
My teacher would throw the chalk at students who were no paying attention! Worse than chalk duster duty was incinerator duty (emptying rubbish bins into the big incinerator)
I think he fell in the water, he got out, and then after that he fell off the cliff.
