I Am My Own Grandpa...

For a bit of a genealogy mind bender, consider the lyrics to the song I Am My Own Grandpa, written by Dwight B. Latham and Moe Jaffe.

1. Many many years ago
when I was twenty three,
I got married to a widow
who was pretty as could be.
6. For if he was my uncle,
Then that also made him brother
To the widow's grown-up daughter
Who, of course, was my step-mother.
2. This widow had a grown-up daughter            
Who had hair of red.
My father fell in love with her,
And soon the two were wed.
7. Father's wife then had a son,
Who kept them on the run.
And he became my grandson,
For he was my daughter's son.
3. 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.
8. My wife is now my mother's mother
And it makes me blue.
Because, although she is my wife,
She's my grandmother, too.
4. To complicate the matters worse,
Although it brought me joy,
I soon became the father
Of a bouncing baby boy.
9. If my wife is my grandmother,
Then I am her grandchild.
And every time I think of it,
It simply drives me wild.
5. My little baby then became
A brother-in-law to dad.
And so became my uncle,
Though it made me very sad.
10. For now I have become
The strangest case you ever saw.
As the husband of my grandmother,
I am my own grandpa!

This song has been recorded by many artists, including Shel Silverstein, Lonzo & Oscar, Homer & Jethro, Ray Stevens, and Dave Grisman. It reportedly was inspired by an anecdote that Mark Twain related in a book, proving how a person could become his own grandfather.
