I haven't seen the video, but it can't be much worse than my psycho marching band director
He was pretty bad!!!
I'm pretty sure some football coaches are pretty crazy too (at least I KNOW they are in certain parts of Texas).
I don't like cell phones in schools period, but that's just my opinion.
For the record - I'm not condoning how the teacher behaved. Sometimes teachers get pushed to the edge by their students. I obviously do not know this teacher or how his students behave normally in class, so I'm just making a statement, that sometimes it does happen.
When I was in school, in 4th grade, I distinctly remember our new teacher. My class was BAD. I will seriously never forget the day she completely blew up and started yelling. I honestly don't blame her. Our class was terrible, but after that day we never were again!
