Read, listen, or print the following lyrics to the song.


Clearly draw a pedigree of this manís family.


There is no need to identify any traits. Make sure you identify each member of the family by name and precisely show all the relationships to explain how "he's his own grandpa" on the pedigree.


Do the work on your own; no help from any other student.


Hand in the pedigree only ďon or beforeĒ the announced due date. No credit for just boxes and circles and random lines, must be easy to see the relationships.





Many, many years ago when I was just twenty-three,

I was married to a widow, she was pretty as could be.

This widow had a grown-up daughter who had hair of red

And my father fell in Love with her. Soon they too were wed.


This made my dad my son-in-law--changed my very life!

My daughter was my mother because 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 he then became a brother-in-law to Dad.

Well, that made him my uncle--made me very sad!

Because if he was my uncle then he also was a brother

To the widow's grown-up daughter, who, of course, was my stepmother.




My father's wife then had a son who kept them on the run.

And, of course, he became my grandchild because he was my daughter's son.

My wife is now my mother's mother and this makes me blue

Because although she is my wife, she's my grandmother too!




Now if my wife is my grandmother, well, then I am her grandchild,

And every time that I think about this, it nearly drives me wild!

Because now I have become the strangest case that you ever saw

As husband of my grandmother, Iím  my own grandpa!






I'm my own grandpa! I'm my own grandpa!

It sounds funny, I know, but it really is so!

Oh, I'm my own grandpa!
