Flies Know What Crap Smells Like

This is great.  As most everyone knows, flies are drawn to the smell of crap.  And I have been told that usually where they land they let a crap themselves, that is why they are a very dirty insect.  These flies must have had a good smell for crap, due to where they landed and buzzed around.  If this story and video's to watch don't tell a story relating to flies, I don't know what will.
