Unacceptable Behavior?

I told the bossman the other day that he needed to go to this seminar. I failed to mention that his behavior is totally unacceptable and needs anger management courses himself. He throws these hissy fits when things don't go as expected. I've expressed to him before in a perfect world, everything would work out ok but this is far from a perfect world. When I first started working here, I would have to go into the restroom and lock the door and laugh at him. He's torn the door from the hinges because he's so mad that he cannot operate a doorknob. Think I'm exaggerating? He's called employees stupid to their face...if he EVER does that to me, he'll see just how far I can throw a stapler and how precise my aim is...
