Instead of "funny", I was about to write "horny". Thinking of male political candidates eager to win (girl)friends and influence people, Confucious might have said: Every election is an erection. But it would be a mistake to highlight the purely sexual aspects of what I have to say. In French presidential funniness, horniness is no doubt a significant element, but it's not the sole driving force.
You can never predict what a French president (or ex-president) might do next. Look at Nicholas Sarkozy, for example. Who would have imagined that, shortly after his election, when his legally-wedded first lady walked out on him, he would promptly get himself linked, for the better or for the worse, with a young Italian pop singer? Today, he's involved in a different kettle of fish: the Clearstream affair.
Using all his presidential might, the French president is currently pursuing, in the law courts, a former prime minister, Dominique de Villepin. In a nutshell, Sarkozy claims that somebody tried to frame him, with electoral ambitions in mind, in the context of a Swiss-based banking scandal. So, there'll be lots of legal fun and games in France (for TV audiences) over the next month.
Concerning Valéry Giscard d'Estaing, I can't figure out yet whether the funniness is basically primitive horniness, or whether there might have been (past tense) something far worse at stake, such as a fuzzy desire to be accepted as a vigorous potential pretender to the British throne. For me personally, if were called upon to choose between Prince Charles (accompanied by Camilla) and Giscard (accompanied by Anne-Aymone), I would hesitate for a long moment. All these people have the stuff of monarchy... but there's an obvious passport obstacle in the case of Giscard. Maybe he was trying to solve this problem by means of a union with Lady Diana. I haven't had time to examine all the details of the situation, but I would imagine that the following scenario could have been enacted at that epoch:
Phase 1: Giscard, having seduced Diana, obtains a divorce from Anne-Aymone. The president can therefore marry his English princess, and they have a splendid son, say Nicholas Dominique d'Estaing. Automatically, at the desire of Diana, Giscard and their baby are naturalized as British citizens.
Phase 2: The English-speaking people of the planet (even in faraway outposts of the ancient empire such as my native land) are so overcome by the sheer beauty of this new entente cordiale between England and France that they launch a plebiscite aimed at replacing Charles by this glorious dauphin named Nicholas Dominique d'Estaing.
Phase 3: In fuzzy circumstances coordinated by the efforts of the European community in Brussels, with a little help from George Bush (who never really understood the possible consequences of what he was doing), Elizabeth accepts the idea that the next king of England should be Nicholas I.
Ah, if only events had happened like that! The world at large would have had fabulous reality resources for TV, and idiots like me would have been able to talk at length about these celebrities on the Internet.
