Tipping the Scales
The term “red herring” denotes a deliberately misleading clue or diversion. This was first used in 1807 by journalist William Cobbett when he described using this pungent cooked fish (which turns from silver to red-brown with cooking) as a boy to distract hounds chasing the scent of a hare. The story was used as a metaphor for the press of the day, which had been distracted from covering essential domestic matters by false news of Napoleon’s defeat.
The term “small fry” to describe a trifling or inconsequential person or thing does not derive from fried potatoes, but more likely newly-hatched fish, also called “fries.”
The term “jumped the shark” is used to describe a television show which has peaked in quality and is now in decline. This began with a Season Five special episode of “Happy Days” in which a waterskiing Fonzie accepts the challenge of a beach rival to jump off a ski jump over a caged shark. This was considered a resort to gimmickry over stronger writing (though the show aired for five more highly-rated seasons, and Henry Winkler got to show off his formidable real-life wasterskiing skills).
