All in a Row

Having one’s ducks in a row is a phrase that relates to getting all of a person’s affairs sorted and became known around the 1980s.  It has been suggested that the expression originated from the fairground amusement game of shooting mechanical ducks.  I myself, as with many others, feel it’s more likely the term came from viewing real ducks.  All one has to do is picture a mother duck taking her brood out for a swim or waddle, and you can see them lining up neatly behind her.
Whatever the actual case may be, these images of linear fowl are nothing short of adorable!
