When my daughter was much younger, my wife was reading to her from a picture book about a snowman who came to life and befriended a young boy, and on each page they would do a particular activity: build a snow fort, slide down a hill, enjoy a bowl of soup and so on. The last three pages had the snowman walking, then running, and then flying. At which point my wife got an unhappy look on her face and said ‘A flying snowman? That’s just ridiculous!’
To which I said: ‘So you can accept a snowman eating hot soup, but not flying?’ Because, you know, if you can accept the former (not to mention the entire initial premise of a snowman coming to life), I’m not sure how the snowman flying became qualitatively more ridiculous.
‘The Flying Snowman Problem’ works as well as a label for the issue as anything, and better than most. Consider it named.
