A messy predicament. This term is believed to come from a Scottish custom of holding a riverside picnic, itself called a “kettle of fish,” where freshly caught live salmon are thrown into a kettle boiling over an open fire and then are eaten out of hand, definitely a messy procedure. Sir Walter Scott described just such a picnic in St. Ronan’s Well (1824), but the transfer to other kinds of messy predicament had already occurred in the early eighteenth century. The term appears in Henry Fielding’s Joseph Andrews (1742) and works by Dickens, Hardy, Shaw, and many others, but it may now be dying out, at least in America.

Accusing a person of faults one has oneself. The term dates from times when most cooking was done over open hearths, where the smoke tended to blacken any kind of utensil being used. The earliest references to this saying in print date from the early seventeenth century. Among the blunter versions is John Clarke’s of 1639: “The pot calls the pan burnt-arse.” A modern and more straightforward equivalent is Look who’s talking, which William Safire believes is derived from the Yiddish kuk nor ver s’ret. In Britain, put as listen who’s talking, it dates from the second half of the twentieth century.
