I've always thought that being an idle sod, I should have taken up journalism. The way it seems to work is that there is a cardboard box full of about 100 stories (maybe these days it been digitised, but the principle is the same).
As you print the story (coach load of pensioners overturns, rottweiler in horror kiddy attack, police in corruption shock, or whatever) you file it at the back, then work through your stock of stories till it turns up again.
So today - oh look - it's the 'police radar locks onto jet' story. Just check that the RAF still operates the Tornado and off we go!
