The Voice Of Authority: A Language Game

Do this. Don't move. O'Grady says do this,
You get a move on, see, do what I say.
Look lively when I say O'Grady says.
Say this. Shut up. O'Grady says say this,
You talk fast without thinking what to say.
What goes is what I say O'Grady says.
Or rather let me put the point like this:
O'Grady says what goes is what I say
O'Grady says; that's what O'Grady says.
By substituting you can shorten this,
Since any god you like will do to say
The things you like, that's what O'Grady says.
The harm lies not in that, but in that this
Progression's first and last terms are I say
O'Grady says, not just O'Grady says.
Yet it's O'Grady must be out of this
Before what we say goes, not what we say
O'Grady says. Or so O'Grady says.
