Professional Troublemakers

What's the worst thing you've ever done?
Whatever it is, I bet what I did is way worst. I mean, unless you did something worst than killing your chemistry teacher than yeah, what I did is way worst.
The thing is, it was all an accident. An accident that got me send to USA's toughest military school. But the moment I step foot on the campus, I knew for a fact that it wasn't just any ordinary strict school. I mean the first thing the secretary said to me was, "Welcome to TreeLog Military School for the Troubled where young prankster learn to become professional troublemakers."
