I'M MY OWN GRANDPA

It sounds funny, I know, but it really is so....
Oh, I'm my own grand-pa!.........
I'm my  own grand- pa
I'm my own grand-pa
It sounds funny I know, but it  really is so...
Oh,  I'm my  own grand- pa.

Now many, many years ago when I was twenty-three
I was married to a widder who was  pretty as can be.

This widder 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.
My daughter was my mother for 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.

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 widder's grown up daughter, who, of course, was my step-mother.

Father's wife then had a son who kept him 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.

Now 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 grandmother, I am my own grandpa.
