eat one's hat, to

To declare one’s readiness to consume one’s headgear if a statement should prove false, an event should not occur, and so on. The likelihood of actually doing so is presumably very remote, which is the very analogy being drawn (to a statement’s being false, an event not occurring, and so on). The expression appeared in Dickens’s Pickwick Papers (1836), in the words of one clerical gentleman, “Well if I knew as little of life as that, I’d eat my hat and swallow the buckle whole.”See also: eat
