[Disclaimer: I actually watched this before Christmas, but didn't have a chance to write a post at the time. And it took me ages to find the right episode again on the BBC iPlayer].
...when you watch an episode of "Pointless" and the theme for one of the rounds is "Countries that have hosted both the Olympic Games and the football World Cup". They were looking Summer or Winter Olympics, and Men's or Women's World Cups.
And these are your responses when each of the players gives an answer:

Japan - "Had the Olympics in Sapporo and Nagano; don't know if they hosted a World Cup"

Russia - "Had the Olympics in Sochi; don't know if they hosted a World Cup"

Germany - "Had the Olympics in Garmisch and Oberstdorf; don't know if they hosted a World Cup"

South Korea - "Had the Olympics in Pyeongchang; don't know if they hosted a World Cup"

Austria - "Had the Olympics in Innsbruck; don't know if they hosted a World Cup"

America - "Had the Olympics in Salt Lake City, Lake Placid and Squaw Valley; don't know if they hosted a World Cup"
Bit of a stuck record, aren't I?!
Checking the list of host cities afterwards, it turns out that Germany has only hosted the Olympics once - Garmisch in 1936. I would have sworn that Garmisch and Oberstdorf had both hosted it twice!

Two places that did host it twice were Innsbruck and Lake Placid. I knew Innsbruck had hosted twice, but I didn't realise that Lake Placid did too.
My mistakes about Germany and Austria are all down to following ski jumping. I had a feeling that Bischofshofen hadn't hosted an Olympics, but I was convinced that all the other venues used in the 4 Hills had been used in 2 Olympics.
I always struggle with Olympics questions, because my brain only thinks in terms of the Winter Games. For the Summer Games, the only hosts I can ever remember are Barcelona in 1992 and Rio de Janeiro in 2016. And that is only because of motorsports connections. The Circuit de Catalunya was used for the cycling in 1992; and the Jacarepaguá circuit was destroyed to make way for the Olympic Village in 2016.
As for the World Cup I don't think I could name
ANY hosts, be it Men's or Women's. I have no interest in Men's football, so I have a good excuse there. But, I watched a few Women's World Cups in their entirity (that was before the sport became popular, and got spoiled). Yet, I can't remember now where they were!
