From Jon Henley’s diary in today’s Guardian…

Worrying news, now, from Mensa, which in the December issue of its eminently readable magazine advertises a social event for members at the Royal Air Force Club in Piccadilly on Friday December 30. Our calendar, we see, says December 30 is a Saturday. But perhaps they know something we don’t.

This is delicious. According to Wikipedia Mensa is “a society for bright people, the only qualification for membership being a high IQ”. A more sardonic way of putting it would be to say that it’s a club for people whose aptitude for certain kinds of meaningless puzzles leads them to believe that — to use the venerable Glaswegian phrase — “their shite is marmalade”.
