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
verse 2
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
repeat #4
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
repeat #4 x2
