I would suppose that you are working on the principle that if you repeat a lie often enough, others will begin to believe it. Sadly, this is often the case.
However, the lie re: your qualifications as an 'expert' in anything will take a record number of repetitions for it to gain any credence whatsoever.

Were it to be true, I would be proud to be from a native Australian tribe whose rich and historic culture fills me with awe, but sadly a native born Englishman is my lot in life. I'm surprised that your Stasi informer training hasn't so far allowed you to work that out, but then you've never been very perceptive have you ?
