... and then there was this time that the Duke of Edinburgh went on a courtesy visit to an asylum. He was shown around, and noticed an unusually quiet chap in a locked cell. He wanted to speak to him, so the nurses unlocked the door and allowed him in. The inmate looked up from the book he was reading and greeted him. 'You seem to be very calm; why are you in here..?', inquired the Duke..? 'An accident, I'm afraid' replied the patient. 'I came to give this book to a friend in here, and I've been mistaken for a lunatic ever since. It's been four years, but no-one will listen to me.'. 'Well, well, well..!' declared the Duke. 'I'll have a word with the Direction here, and we'll get this sorted out pretty quickly. Trust me; I have some influence.' He turn back to the door to leave, and was hit on the back of the head with the heavy book. 'And don't you f***ing forget, neither..!' screamed the inmate.
