H. L. Mencken:

In the American colleges and high-schools there is no faculty so weak as the English faculty. It is the common catch-all for aspirants to the birch who are too lazy or too feeble in intelligence to acquire any sort of exact knowledge, and the professional incompetence of its typical ornament is matched only by his hollow cocksureness.
