Most creative shit students have done?

What is the most creative shit students have done in your school? Things you're still wondering how they did that, things that if they were putting as much energy in their schoolwork they would be top students

I start:

1. A year 12 guy defrauded the school, the same guy who once bought all the sandwiches of the cafeteria and ate them all the same day, he also tampered his electronic card so when you scan it with your phone Rick Roll starts playing

2. A bunch of year 10 students organised a BBQ party in the school bcs they said "the food at the canteen is barely edible and it's said nowhere it's not allowed", they gave sausages to the headteacher and other member of staff to not get sanctions, now there's a line in the policy that says "BQQs aren't allowed on the school ground"

Bonus: it was a few years ago when I worked in france, macron said that girls shouldn't be wearing crop tops for school but "republican outfits" instead, the very next day all the girls of the country including mine came to school wearing crop tops and some even came topless in reference of the painting "Liberty leading the people" by Delacroix and the allegory Marianne
