Two sisters we are, one is dark and one is fair,
In twin towers dwelling we're quite the pair,
One from land and one from sea,
Tell us truly, who are we?
The front of me is the source of a song
Or to kiss with a fervor of love lifelong.
My back is a plant fit for a queen,
Crafted by needle, chemical, or machine.
Four jolly men sat down to play,
and played all night till break of day.
They played for gold and not for fun,
with separate scores for every one.
Yet when they came to square accounts,
they all had made quite fair amounts!
Can you the paradox explain?
If no one lost, how could all gain?
A man while looking at a photograph said, "Brothers and sisters have I none. That man's father is my father's son."
Who was the person in the photograph?
