For me it was putting Grand Theft Auto Vice City on the school computers shared folder last year so that everyone had something to do after their exams were over (i did it approximately 3 weeks before exam weeks). Every teacher in the school knew GTA was on the computer but couldn’t find it from how well I hid it, and every student knew where it was and that I was the one who did it, but no one would snitch on me because they loved me for what I did! What about y’all? Anything cool or big you did and never got caught for?
