I remember seeing something by Professor Lembecke about the origin of the phrase but I can not find it at the moment. Addendum: I looked a little more I cannot find the reference. I think it was probably in The Spitting Image. I also would like to thank you for not commenting on the sentiment. In my opinion the phrase has a large personal component and it is impossible for a complete stranger to form a well reasoned opinion on the authenticity of the sentiment.
