Famous quotes containing the word hat:
““If the law supposes that,” said Mr. Bumble, squeezing his hat emphatically in both hands, “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.””
—Charles Dickens (1812–1870)
