I’m apparently in that part of the human race that doesn’t ‘get’ the following paragraph. If you are in the other part, please a) wipe that smirk off your face, b) explain what I’m missing (ideally, preceded by a hint). Thanks!
The old church. Old lady: ‘We have a very old church here, 1913.’ ‘Oh, auntie dear, you mean 1319.’ ‘Not at all, my dear, 1325.’ (This sharply divides the human race.)
Context & credits: The quote above is from the chapter ODDS AND ENDS of the book “Littlewood’s Miscellany,” by John Littlewood and Bela Bollobas. That particular chapter is a collection of brief self-contained anecdotes, observations, puzzles, and random other stuff. Littlewood does not explicitly state that this particular item is a puzzle, but I think that's a safe bet; at any rate, it puzzles me!
I should add that, while Littlewood was an eminent British early 20th century mathematician. Most of the Miscellany, including the chapter from which this quote was taken, is directed at the intelligent layperson.
