Like the hero of Evelyn Waugh's "A Handful of Dust", one can imagine David Cameron ending up, through a conspiracy of events, in the Amazonian jungle forced to recite "Ernie" to a cannibalistic tribe for the rest of his life. It would serve him right.
I remember when the innocuous Gay Byrne, on Irish TV, beguiled the Tory Northern Ireland secretary Peter Brooke into signing "Clementine" on his show. It was flesh-crawlingly embarrassing and, even now, Peter Brooke has probably not lived it down. The clip still gets played now and then on the box.
Well, now there is a marvellous opportunity waiting for David Cameron to be asked to recite all the words from "Ernie" just to prove he really can remember all 600 words. That'll be one for the clip shows.
