I've got 2, both from middle school:

1. No card games: Like, why? I even had a classmate who during one period didn't exercise on PE. Perhaps due to previous sickness, I don't remember. As he wasn't the only one, he played some card game with others. The PE teacher noticed it, took that card deck, AND FUCKING RIPPED IT IN HALF. How much strength does that...? Anyway, I remember he cried, I'd say rightfully so. "You are supposed to pay attention!" Pay attention to what, people running?
   Card games were even banned during breaks, not just free classes. What's the problem? Teachers didn't care if someone was beating the shit out of someone else with a chair, they didn't care if someone was playing with a butterfly knife, but card games? "That's dangerous for the youth."

2. No smartphones: I mean, not even during breaks, except for "A" classes. A classes had the "better" students. The weirdest stuff here was that I haven't taken the phone with me to school. After all, why? I could break it, I'd have no use for it and I lived 2 minutes away from school. But, when it came to collecting them, no one believed me. "Everyone has a phone nowdays, so you'll either give it to me, or I'll have to search your bag." Thankfully, after a week our class teacher finally understood that I in fact do not carry a phone with me.

Or perhaps I could also add something from elementary school. I have no idea what rule it would break though:

Some girl reported me (a boy) for apparently having a mascara. Our teacher then searched my bag, as if it was a grenade. I did in fact not have it.
And no, she didn't report me stealing a mascara, just me having one as a boy. And the teacher took that seriously.
