It's funny how some people make up "signs" to help themselves recognize and remember things.
Many years ago while at Concord Hospital I remember seeing a bowel gas sign which reminded me of a croissant and exclaimed "oh the croissant sign!" which sent several colleagues scuttling to their text books in search of a sign that I had just made up.
More recently some clients have mentioned the "turtle" sign which indicates a male Bub. So I have been paying a little more attention and they seem to be everywhere (see collage).
