It sounds funny I know, but it really is so,
O-oh, 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,
O-oh, I'm my own grandpa.
Now, many, many years ago when I was twenty-three,
I was married to a widow who was perdy as could be;
This widow had a grown-up daughter who had hair of red,
My father fell in love with her and soon they too 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 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 widow's grown-up daughter who, of course, was my step-mother.
Oh! I'm my own grandpa. [Yes I are!] I'm my own grandpa,
It sounds funny I know, but it really is so,
O-oh, I'm my own grandpa.
Father's wife then had a son who kept him on the run,
And he became my brother for he was my father's son;
My wife was 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 am her grand-child,
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.
So! I'm my own grandpa. [No 'bout adoubt it!] I'm my own grandpa,
It sounds funny I know, but it really is so,
O-oh, I'm my own grandpa.
It sounds funny I know, but it really is so,
O-oh, I'm my own grandpa.
