Grammar God

But we knew that already, didn’t we?

Grammar God!
You are a GRAMMAR GOD!

Congratulations! If your mission in life
is not already to preserve the English tongue,
it should be. You can smell a grammatical
inaccuracy from fifty yards. Your speech is
revered by the underlings, though some may
blaspheme and call you a snob. They’re just
jealous. Go out there and change the world.
