As a stunt for Capping Week (I think it was, or Fresher’s Week), a small group of us created and posted official-looking notices around the library and on all the noticeboards advising that, with immediate effect, all toilets had been de-segregated.
Our prank caught the eye of the dear old Evening Post and elicited public comment and condemnation from a number of luminaries, including the then-head of a well-known local private boys school.
