The Disruptor, by Bobby Warner

When I stepped into the classroom all the kids started making snide remarks and throwing things at me.

I set my books on the desk, turned to face them, hoping the scowl on my face would intimidate them. It didn't. Someone sounded a raspberry; someone else hit my forehead dead center with a rotten tomato. The whole room was out to get me.

Then the teacher yelled: "Sammy, go immediately to the Principal's office. I've warned you enough about being late and disrupting the class!"
