Two men, one American and an I...
Two men, one American and an Indian were sitting in a bar drinking shot after shot.
The Indian man said to the American, "You know my parents are forcing me to get married to this so called homely girl from a village whom I haven't even met once. We call this arranged marriage. I don't want to marry a woman whom I don't love... I told them that openly and now have a hell lot of family problems."
The American said, "Talking about love marriages... I'll tell you my story. I married a widow whom I deeply loved and dated for 3 years. After a couple of years, my father fell in love with my step-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 is 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?"
