One day a kid from class overflowed the boys bathroom toilet. You must be thinking, "that's not to bad" well, the sewage backup caused a chain reaction that caused all the other toilets that shared the tubing to overflow as well. And in the case of my school, it was all of them, and my school is HUGE, so you could imagine all of the chaos that ensued. Every square inch of school flooring was covered in shit water, and some of it was week old shit. It took about a month of cleaning to get it all cleaned up, plus thousands of dollars it took to fix the piping. And even months after the incident, it still smells like poop, and there is now a note in every bathroom to not use a lot a TP. The end.
