When told that "the law supposes that your wife acts under your direction," he replied, "If the law supposes that ... the law is a ass — a idiot. If that's the eye of the law, the law is a bachelor; and the worst I wish the law is that his eye may be opened by experience — by experience."
It's often truncated to "the law is a ass - a idiot" but that misses the whole point of the exchange (Mr. Bumble was thoroughly henpecked by a wife even more horrid than he was.)
(the omission of the alliding 'n' in the indefinite article is a marker for the reader of Mr. Bumble's extremely 'umble h'origins, and 'is attempts to disguise them . . . )
