Ah malone we are of like minds! Richard Osman wrote in his book, A-Z of Pointless, that the authorities had "shown Alexander [Armstrong] and I round the set". I wrote to him asking who they would have shown round had Alexander not been present? He did not bother to reply, needless to say. However it has always been clear to me (as pointed out by a subsequent contributor - was it chrisse?) that if you remove the attendant person, it all becomes quite clear. What is worrying is that schools no longer correct wrong grammar or misspelling and even the BBC with its 500 words competition, insists that grammar and spelling are not important.
