Thou shalt not covet Mr. Sotheby’s Muse,
His Pegasus, nor anything that’s his;
Thou shalt not bear false witness like “the Blues”—
(There’s one, at least, is very fond of this);
Thou shalt not write, in short, but what I choose:
This is true criticism, and you may kiss—
Exactly as you please, or not—the rod;
But if you don’t, I’ll lay it on, by G‑d!
