Many, many years ago, when I was twenty-three,
I got married to a widow who was pretty as could be,
This widow had a grown-up daughter, with flowing hair of red,
My father fell in love with her, and soon the two were wed.
This made my dad my son-in-law and changed my very life,
My daughter was my mother, for she was my father's wife,
To complicate the matters worse, although it brought me joy,
I soon became the father of a bouncing baby boy.
Father's wife then had a son, who kept them on the run,
And this made him my grandson, for he was my daughter's son,
My wife is now my mother's mother and this makes me very blue,
Because, although she is my wife, she's now my grandma too.
If my wife is my grandmother, then I am her grandchild,
And every time I think of this, it simply drives me wild,
For now I have become the strangest case that you ever saw,
As the husband of my grandmother, I am now my own grandpa!
