It's the herring that will perish.

I simply couldn't pass up sharing this passage from Sister Bernadette's Barking Dog (a book about English grammar):

Standard Enlgish is, of course, the version of the language that has resulted from years of hand-wringing about the speed with which it has changed. But to try to hold back language change is like trying, as Monty Python and the Holy Grail would have it, to cut down the largest tree in the forest with a herring. The tree will keep growing. It's the herring that will perish.

I thought so.
