A while back when I was in a job with time on my hands I sent an email to the press office at Canadian National Railways to point out that the US broadcaster CNN had ripped off their logo style – just added an extra ‘N’. Charmingly, the railways PR emailed back and said I was misinformed! And in fact they are totally different. That’s the kind of dumb thing you do when you have too much time on your hand.
