I had a friend who is on the sex offenders registry for life because when he was 17 he put gay porn on his teacher's laptop as a prank. Haha, I thought it was funny and harmless.

Kids playing jokes and harming poor sensitive teachers' fragile minds: you need to knock on your neighbor's doors and tell them you're a sex offender for the rest of your life. Teacher masturbating with middle schoolers: naughty naughty, temporary leave for you!
