'I suddenly remembered a patient on the Neurology Wards 15 years before, who had woken from sleep, one Christmas Day, to find ‘a strange leg’ in his bed. There was a Christmas party going on, and the only ‘explanation’ he could imagine was that one of the nurses, as a joke, had filched a leg from the Anatomy Room, and slipped it under the covers as he slept.'
