Big Mouth Billy Bass was a novelty animatronic fish that became a popular gag gift in the late 1990s, mounted on a plaque and programmed to turn, flap and sing when someone walked past. Its signature routine used Take Me to the River, a soul song first made famous by Al Green in the 1970s, which gave the joke an earnest musical backing. Videos of the fish performing in living rooms, offices and bars spread online, turning it into shorthand for kitsch, dad humour and fishing culture, and creators still reach for it whenever a cheap, recognisable punchline is needed.
