Now, many many years ago
When I was twenty three
I was married to a widow

Who was pretty as could be

This widow had a grown-up daughter

Had 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
'Cause she was my father's wife


To complicate the matters
Even though it brought me joy
I soon became the father

Of a bouncing baby boy

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
That also made him the brother

Of the widow's grown-up daughter
Who, of course, was my step-mother


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 father's wife then had a son
That 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, 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


Now, if my wife is my grandmother
Then, I am 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 the husband of my grandmother

I am 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

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
