Any concrete example of BNCF ???

Hello Joe, and everybody !

I might have only ;-) all Joe's books, but I am looking after a very explicit example of a BCNF (normal form) to make them understand what is the trouble.
Did you have a good one, especially one I could transpose in french way of life (I mean not with US Zip code, or health insurance registration number) ???

Thanks in advance
