I'm my own Grandpa

The comedy song "I'm My Own Grandpa" is a novelty song written by Dwight Latham and Moe Jaffe in 1947. It is a song about a man who, through an unlikely (but legal) combination of marriages, becomes stepfather to his own stepmother. The song pays no attention to the prefix “step-” however. As a result of this (hopefully) unlikely scenario, the singer becomes his own grandfather. It has been recorded by various artists including Ray Stephens and Willie Nelson. More recently it was used in the highly popular cartoon series "Futurama".

"I'm My Own Grandpa"

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
