People used to sing the opening line of this school hymn:

The land is yours oh God,
You nourish it with rain.

This was popular because if sang in a certain manner, an all too obvious expletive could be constructed:

The land is yours oh god,
You nouriSH IT with rain.
The word SHIT was over emphasised and everyone at Ley Hill Middle School (Sutton Coldfield) was in on the joke... thus making for particularly amusing assemblies.
