Not neccessarily hard and fast rules, but certain policies in my elementary and high schools made me alternately smile and shake and my head in disbelief.
My elementary school is deathly afraid of lawsuits. If a single child is lightly injured doing anything no matter how stupid, they will ban that activity for everyone. There was a nearby forest that was kind of fun to run around in, that got banned. Then they banned their own playground (which they had put in only a few years ago likely at great expense) for everyone below Grade 4 because someone hit their head on the bars. No tire swing because someone tried to eat it. No snowball fights either.
My High School performs fire drills more often than the faculty wanted to, because people were into the habit of hitting the alarms for fun. The alarm means everyone runs out into the field with what you were wearing inside the classroom, regardless of weather, after which it may take as long as half an hour for them to get organized and march everyone back in. Normally this is just a minor inconvenience, but when that happens in my drama class during winter, where everyone takes their shoes off so as not to damage the carpet... yeah. Thankfully, that only happened once. The other funny thing about it is shortly after a fake fire alarm or the shattering of a window they will offer cash rewards over the PA for information on who did it. Never found out if that ever worked, but I doubt it.
