I remember some ridiculous antics regarding bathrooms when I was in Grade 11.
My high school was a 4 storey building which had a boys and girls bathroom on each floor.
One day early in spring, some dude shit his pants and, unsurprisingly, didn't want anyone to know about it, so he shoved the

in the toilet, and cleaned himself up with a shitload of hand soap and toilet paper. My high school was fairly new, but it had been built just before low-flow toilets were mandated, so when the next kid took a dump, it got stuck on top of the DIRTY, CRAPPED BRIEFS, he panicked and started flushing like mad. It was the 4th floor bathroom too, so it created a biohazardous shit slide that went down the nearby stairwell.
Administration's response to this was really childish, however. They assumed it had to be a prank, and closed all the boys bathrooms except for the one on the first floor until someone copped to it.
We had our suspects, but first a bit of background: That year, since the uniform warehouse was really far from the school and didn't offer online shopping back in the early-mid aughts, the school opened a tuck shop in the cafeteria in a disused storage room. It was staffed by the students in the adaptive skills/ resource program to give them a workplace experience in a sheltered environment and teach them skills they could actually use.
One of these kids reported that a guy had rushed in, all sweaty, and panicked looking and bought a pair of gym shorts, making him the prime suspect. Also on the list were the 5 or 6 profoundly disabled "rubber room" (as opposed to "resource room") speds, and an otherwise ordinary, decently well liked guy who had been complaining of gastro/ a stomachache.
After about a week of this BS, we were all pretty annoyed. Some "niner" said what we were all thinking: didn't the teachers, VPs, and principal remember high school at all? No kid would ever admit to shitting their pants; it would be social suicide.
We also didn't really believe that any of the suspects could be proven to have done it. The kid who bought the gym shorts insisted he was sweaty because it was gym class, and he bought new shorts because he split them, and the tuck shop was staffed by kids who weren't the brightest anyway. We had a very protective attitude about the rubber room kids, so we wouldn't blame them if they did, and even that wasn't every likely, because they almost always had 1-on-1 or 1-on-5 supervision and could use the handicapped bathrooms. The dude with gastro- well, how could prove that?
After about 2 weeks of that, administration gave up and opened up all the bathrooms, not least because some kids were skipping class under the excuse that they had to go down 4 flights of stairs and then wait in line for the bathroom.
About a month later, some dumbass guy decided to have a smoke in the 3rd floor boys' bathroom. Instead of using the sink or toilet, he chucked his cigarette butt and a hot lighter into a garbage can filled with paper towels and toilet paper. Unsurprisingly, it started a fire, and set off the alarm. They had to evacuate the whole school onto the running track. The fire department came, but it was a janitor who put the fire out with his mop bucket so there was no chance for it to spread.
They closed all the bathrooms except for one again as if that would solve everything. The student body was fed up with it at this point, and some parents started to get involved.
The prime suspect at this time was Dick (using pseudonyms) who was this kid that nobody liked because he was, well, a huge dick. Dick was suspected of doing it because he reeked of smoke all the time. He claimed it was because his parents were chainsmokers and smoked inside their apartment. Eric, a kind of quiet kid that was well liked called him out on it. Dick told him to STFU or fight, and Eric elected to fight. Eric was also in much better shape and a full head taller than Dick.
Because hundreds of high school kids can't keep a secret, the principal got on the PA and announced that anyone caught fighting or even watching a fight risked suspension.
What happened was the fight took place in a park, 300 kids came to watch, Dick got his ass kicked, the neighbours called the school board, the bathrooms got re-opened, and the principal got transferred the next year. Nobody wound up getting suspended. The vice principal who went over to break it up was too late. You couldn't suspend most of the grade 11 class. Dick's reputation actually improved slightly because he didn't rat out Eric (he said he got jumped by kids from another school) and got his ass kicked fair and square with no below the belt or bitch moves
