I remember a big scandal at my local catholic school when I was about 12, it was run by the local nuns who didn't take any prisoners when it came to down to any defiance or misbehaviour by us pupils.
One year about 10 of them went to Africa on some kind of nun exchange type system for 6 months or thereabouts, 7 of them came back bleeding pregnant, the shame of the nuns forsaking their vows forced the local council to take over the running of it.

So much for morality eh.
