Well that should sort out the genocidal maniacs who fill out forms honestly from those who don't quite effectively
...and, um, ex Prime Ministers
Having said that there was one time when I filled in a visa entry form, into New Zealand as I recall, with a dozen questions like - 'Are you are spy?', 'Are you a wanted criminal?' 'Are you a wanted terrorist?' and some bureaucrat with a sense of humour had hidden a question like 'Are you NOT a drug smuggler?' in the middle somewhere - just ticking the 'No' box twelve times without reading the questions wasn't a good idea
How we laughed at the desk as the customs official reached for the rubber gloves...
