My Mum has just sent me this; I don't know from what source but it amuses one:

I was on National Service in the Royal Signals, Catterick, Yorkshire. I was a sergeant instructor on a training course for radio mechanics. The final course test was for the trainee mechanics to repair a defective radio. In preparation for the test we would put about eight defective pieces into the circuits of 15 radios. The trainees had a fixed time of two hours to identify the defects in their radio and make the necessary repairs. The proof of success was to tune into a BBC station. On the morning of the King's death nobody knew that BBC transmissions were suspended. So after three hours with no radios working, exasperated trainees and instructors went for lunch and then slowly realised what had happened.
