Ducks

Why is it so hard to get all of your ducks in a row?
Because ducks naturally prefer columns. When ducks line up to cross the road, it’s in a column, not a row.
Problem is, a column takes longer to cross the road. Ducks crossing as a row all reach the other side at the same time.
But then, a column of ducks offers a lesser profile, and are harder for you or your car’s radar system to see. So, if one gets hit, they all get hit.
When it comes to rows and columns, I don’t get ducks.
