Get your ducks in a row
Three sleeping ducks on the River Nidd.
The left hand two appear to be balanced on one leg. I have always wondered how they manage this without being blown off.
And now for today's useful nugget of information:
Get one’s ducks in a row and have one’s ducks in a row are American idioms, the origin of these phrases is murky. One possible origin is a lawn bowling game that was popular in the 1700s, which involved setting up duck pins, obviously, in a row. Another possible inspiration for the term get one’s ducks in a row is the way in which tin ducks are lined up in a shooting gallery. A third possibility comes from actual ducks and the way in which ducklings line up when following their mothers. Other theories abound too.
