His attitude would have caused him to be 'bullied' by the kids who
were fed up with him. There were a couple kids like him, when I was
in school. The only way to stop them was to show them what would
happen, if they kept it up. Like one huge, foul-mouthed idiot who liked
to hit people. He did it with a welding hammer in the machine shop.
Two guys grabbed him, and a third hit him in the balls with his hammer.
Just like he had to another kid, but a lot harder. He had a real change
of attitude, after that.

One might argue that it was not so much a change of attitude, but the
creation of a conditioned reflex.
