APY – Depends on the size of the yeshiva. If it’s a really big one, 4-8 in half a year works out to 8 – 16 in a full year, not entirely unbelievablegiven what’s going on these days. But vnishmartemmeod makes it sound like some kind of plague – like a contagious spiritual flu.
And of course, aren’t ALL yeshivas “metzuyan?” 🙂
Mabye the whole story is apocryphal? It sounds like a frum version of a supermarket tabloid.
