I think that the Beeb and ITV must put adverts in local newsagents windows, asking for really thick people to appear on TV and make complete wassocks of themselves. I have lost count of the number of times that contestants on the Lottery program have been asked really quite simple questions by Dale Winton, and they start their answer by saying ::
" Well Dale, Geography is not my specialist subject ! "
You just know that they are going to say that kangaroos come from Africa, or the Andes are in India, etc, etc !
I had a colleague once that had to drive to Exeter from South Wales for a meeting and when I told her that all she needed to do was to go over the Severn Bridge and take the M5 south, she amazed me by saying that she didn't know anything about compass points. Admittedly, she was a bit on the thick side but how anybody could possibly get into their 40's and not know the difference between north and south is completely beyond me.
