Once two men sat in a bar drinking.
The first one said to the other ,"I have a hell lot of family problems."
The second one said ,"I'll tell you mine.
I married a widow having a young daughter.
My father married my daughter and so my father became my son-in-law and I became my father's father-in-law.
My daughter is my mother and my wife my grandmother.
More problems occurred when I had a son.
My son is my father's brother and so he my uncle.
Situations turned worse when my father had a son.
Now my father's son I.e. My brother is my grandson.
Ultimately, I have become my own grand father and I am my own grandson.
And you say you have family problems".
