The School is not Your Toilet!
Most people dump their waste is the correct utensil but some "Take 'Funny' way too far people" dump their waste in a sink, urinal, or even a trashcan (I've seen it!) Most people witnessed the "Stinky Brick accident" and laugh at it. To be honest, I laughed to, but really, it is not something to laugh about. If you or anybody sees, or does something like that, I would tell right away. Telling a teacher or adult is not being a taddle tale, it is doing the right thing. But seriously, the school is not your toilet, but a toilet is!
