The Family Fortunes question reminds me of a 1991 episode of The Krypton Factor where the quick fire round contained the question "Apart from Tyne Tees, which is the only ITV company to be named after a river". One of the oddest questions I've ever heard.
Well, the question setter *did* have to link it with the answer to the previous question in some way...
(And I'd argue that this question from 1988 is even more odd: "In Paris, it's known as the Boulevard Périphérique; what is such a road known as in English?" It was nonetheless answered correctly.)
Now officially retired from TV Forum. "When the fun stops, stop."
