judaism.stackexchange.com/q/96206/2 looking for a mezuza-technical reason that kids shouldn't break school rules reminds me of the apocryphal story of the guy whose milk kept getting stolen out of the yeshiva dorm fridge until he put a label on it saying "not chalav Yisrael."

@IsaacMoses Surprised we don't have a question about that story-identification.

@Alex If we had a question about identifying every buba meisa out there, we'd have a lot of questions about identifying buba meisas.

Fair enough.
