Most of the stuff I got in trouble for was bunking off sports lessons, although I learned in later years how to fix it so that no-one cared where I was going.
Amusingly enough, I was the only one of my entire friendship group who didn't get busted for smoking at one point or another, despite being just as bad as the rest of them. My "me, sir? no, sir, I would never do that, sir" game was strong (enough).
