has your ch poss het pied proven? poll

I recently heard a comment made that there has never been a ch with the het pied marker prove out to be a het. After reading a thread on here of someones ch prooving I would like to know if there has been any others. If anyone has had a ch or even a normal that they have no clue on its background, petstore purchase etc. That they kept for breeding with the the pied marker that prooved (male/female) could you post a story, with pics? I want to see just how often this has happened.
