Song of the Ventilators.

We are really quite the latest, most attractive up-to-datest Thing in modern ventilators.
There are many potent factors, why intelligent contractors,
And the Council Board have backed us;
For we're neat and ornamental, and our style is Oriental,
And the noise we make is gentle;
But we're really not prepared to, no we certainly don't care to
Condescend to let the air through.
