When I was in elementary school my friend pissed on the fence at the back of the playground because the teacher wouldn't let him go inside to do it. Some kids told on him and the teacher, livid, dragged him into the principal's office trying to get him punished.
He said it was the most awkward moment of his life because the principal immediately turned on the teacher and chewed her out for forcing my friend to have to go outside. He said he just sat there with a thousand yard stare while the principal yelled and his teacher cried.
