At my old high school . . .
No Red or Blue shoelaces [I know why it's a rule, but I asked the woman in the discipline office once if someone like me would even get in trouble for it and she said no . . . which I think just makes them racist. xd ]
Girls can wear trench coats, but not Guys. [I could understand NO trench coats, but not the double standard.]
We had a school news program and in one episode, one person jokingly hit another with a rolled up paper, and the teacher cut it.
Most of the bathrooms got locked at Lunch and Break. You know, the time when people actually use them. Only three, all practically next to eachother, remained unlocked.
My school was pretty great though . . . Because I was in the school news program and the admins knew it, I could walk around the halls without a pass, especially if I was just holding a camera. We went to the Grocery Store during class. It was so easy to ditch.
Edit: Ugh, this one was really stupid. My friend took out her cell phone after school, 5 steps away from the door, and the metal shop teacher told her no phones in school. Literally, by the time he got through saying it, we had already opened the damn door.
