Family Tree Joke

Many, many years ago
When I was twenty-three,
I got married to a widow,
Pretty as could be.
This widow had a grown-up daughter
With flowing 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.
Now my daughter was my mother,
For she was my father`s wife.
To complicate the matters worse,
Although 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
to the widow`s grown-up-daughter
Who, of course, was my stepmother.
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,
My wife is now my mother`s mother
And it makes me blue.
Because, although she is my wife,
She is my grandma too.
If my wife is my grandmother,
Then I am her grandchild.
And every time I think of it,
It simply 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 !
