The infamous Charles and Di Kit Kat ad. Was it clever? Very. Was it humorous? Certainly. Was it one of the few good newspaper ads that ran last year? I, as an advertising art director, think it was. Was it malicious? No. Was it offensive? No. Was it hinting at anything other than reality? No. So what's all the fuss? I assume most of those who complained are British people deficient in their mother country's legendary sense of humour. Let's face it, chocolate is a fun product and as such the best way to promote it is by using humour. There was a time when all or most prominent members of the British Royal family behaved, in public at least, in a manner befitting their roles as representatives of their once-great nation. But over recent anni horribilis it is not unreasonable to say that their antics have brought them down to a less exalted level; a level where they are ripe for lampooning. Those whingeing poms who wrote in because they don't like the ad or found it ''distasteful'' should stop buying the product. But why should they have to spoil good, clever and humorous advertising for people who are not so quick on the ballpoint? I thought it was a great ad and I got a good laugh out of it.
