Twin Idols by Eugene Field — Read

There are two phrases, you must know, / So potent (yet so small) / That wheresoe'er a man may go / He needs none else at all; / No servile guide to lead the way / Nor lackey at his heel, / If he be learned enough to say / "Comme bien" and "Wie viel."

The sleek, pomaded Parleyvoo / Will air his sweetest airs / And quote the highest rates when you / "Comme bien" for his wares; / And, though the German stolid be, / His so-called heart of steel / Becomes as soft as wax when he / Detects the words "Wie viel."
