I watched some of it as well - it was on when I was bringing the teas in, and I noticed right away that Ms Robinson appears to have aquired her new teeth from the Co-Op horse!
It may be that she has had some work done, and joined the legions of slushy speakers -
Hugh Hefner
David Jacobs
Margaret Thatcher
Rula Lenska
John Craven
Stacey Solomon
and no doubt others - feel free to add to the list -
people who are united by their financial resources being sufficient to be able to afford decent dental treatment, but appear to have opted for practitioners who think it's a good idea if their clients sound like they have a mouth full of marbles.
It's a mystery why this happens - don't they notice the change? Don't their loved ones tell them?
