I am not sure if this was first a joke. But...

Shame And Scandal In The Family

In Trinidad, there was a family
With much confusion as you will see
It was a mama and a papa, and a boy who was grown
Who wanted to marry and have a wife of his own
He found a young girl, that suited him nice
And went to his papa to ask his advice
His papa said son, I have to say no
This girl is your sister but your mama don't know

Refrein: Who, is me, shame and scandal in the family
Who, is me, shame and scandal in the family

A week went by and the summer came 'round
And soon the best cook in the island he found
He went to his papa to name the date
But papa shook his head and to him he said
You can't marry this girl, I have to say no
This girl is your sister but your mama don't know
Refrein

He went to his mama and covered his head
And told his mama what his papa had said
His mama laughed, she said go, man, go
Your daddy ain't your daddy, but your daddy don't know
Refrein
