In 1977, at the age of 51, Hugh Hefner endured an existential crisis when he found himself choking on a metal Ben Wa ball, one of a pair that had been in his girlfriend Sondra Theodore’s vagina in order ‘to enhance her physical sensations’.

(I’m quoting from Steven Watts’s 2008 biography, Mr Playboy.) ‘Is this what it has all come to?’ Hefner later wondered aloud. Then: ‘What will all the newspaper headlines in the world say tomorrow morning?’ Finally, regaining his composure, he asked: ‘Are we getting this on videotape?’
