I got this one pointed out to me recently - It shows just how your average newsreader stays sane having to pass on the gloom, doom and despondency that news agencies make their living with. From personal experience - having worked in such an organisation this is mild and fairly good natured. I have seen an anchor who, the moment the transmission lights went off ran screaming from the studio and punched a hople in a partition wall in the make-up room.
I know an anchor that took advantage of not being seen below the waist and read a very sombre news item in black tie and jacket... and the filthiest pair of jeans you've seen in your life! Just a pity pocket video cameras didn't exist back then.
