Nick Clegg, the Deputy Prime Minister, managed to both amuse and amaze his audience this week when, speaking at a lunch for the parliamentary press gallery, he told two jokes. They were both quite funny.
Typically, the jokes that modern politicians tell have none of the wit that used to enliven the House of Commons. Great orators like Lloyd George, Churchill and Michael Foot not only knew how to tell them, they wrote them too, rather than relying on the services of paid joke writers.
Margaret Thatcher was one of the first to require professionals to write jokes for her, because her bossy, orderly mind revolted against the verbal anarchy of humour – but the people she hired were good, and once she had the point of a joke explained to her, the result could be all the funnier coming from someone so remorselessly serious.
In modern times, politicians who write their own jokes are exceedingly rare. Either they have them written by an adviser, or they pick them up second-hand, frequently selecting ones that were not funny the first time.
One of the problems is that the modern 24-hour news cycle means politicians are compelled to be so very careful with what they say, because there is always someone out there ready to be offended.
And with rare exceptions, they are not naturally funny people. If they were, they would probably not be in politics, because the rewards for being a successful comedian are so much greater. People take comedians seriously, while they laugh at politicians, but seldom laugh with them.
