When is a joke about disability and cruelty to animals acceptable? Answer: when it’s cracked by John Trundle, chief executive of charity Blind in Business. Trundle was welcoming guests to his An Eye for Talent project, aimed at helping law firms and others meet talented blind and partially sighted young people to enrich their organisations. The event was attended by an eclectic mix of lawyers, singers, musicians, artists, civil servants, IT specialists, and, of course, Obiter. But as there was no stand-up comedian, Trundle instead shared a joke that had been told to him by former home secretary David Blunkett: A blind man tells his sighted friend that parachuting is one of his hobbies. ‘Parachuting?’ says the friend. ‘But how do you know when to pull the cord?’ ‘That’s easy,’ replies the blind guy. ‘I wait until the dog lead goes slack.’
