There's lovely little story on the blog of Doctor FTSE, which he thinks is probably untrue.
I was exchanging true/untrue stories with a friend last night, and recalled this, which really is true.
I was a young staff nurse, and I overheard the following exchange between a young doctor and an elderly and very deaf femals patient:
Doctor: Do you have any trouble with your front passage?
Doctor: DO YOU HAVE ANY TROUBLE WITH YOUR FRONT PASSAGE?
This was repeated several times. Then:
Patient: Only when my neigbour parks his bicycle in it.
