Many, many years ago when I was 23,
I was married to a wider who was purty as can be.
This wider had a grown-up daughter who had hair of red
My father fell in love with her and soon they two were wed.
This made my dad my son-in-law and changed my very life
For my daughter was my mother cause she was my father's wife
To complicate the matter even though it brought me joy,
I soon became the father of a bouncing baby boy.
I'm my own grandpa,
I'm my own grandpa
It sounds funny I know
But it really is so
I'm my own grandpa.
My little baby then became a brother-in-law to dad,
And so became my uncle though it made me very sad.
For, if he was my uncle, then that also made him brother
Of the wider's grown-up daughter who, of course, was my step-mother.
My father's wife then had a son who kept them on the run,
And he became my grandchild for he was my daughter's son.
My wife is now my mother's mother and it makes me blue
Because, although she is my wife, she's my grandmother too.
I'm my own grandpa,
I'm my own grandpa
It sounds funny I know
But it really is so
I'm my own grandpa.
Oh, if my wife is my grandmother, then I'm her grandchild.
And every time I think of it, it nearly drives me wild
For now I have become the strangest case you ever saw
As husband of my own grandmother, I'm my own grandpa.
I'm my own grandpa,
I'm my own grandpa
It sounds funny I know
But it really is so
I'm my own grandpa.
