What the duck

This is some joke I read somewhere on a random blog..Hilarious.. Two men, one Indian and an Foreigner were sitting in a Bar drinking shot after shot. The Indian Said to Foreigner , you know, my parents are forcing me to get married to this girl from a my town whom I haven't met even once. We call this as arranged marriage. I don't want to marry a woman I don't know. I told them that openly and now have a hell lot of family problems.
After listening to Indian, Foreigner Started: "Talking about love marriages-I will tell you my story. I married a widow whom I deeply loved and dated for three years. After a couple of years my father fell in love with my stepdaughter and finally married her. Now my father became my son-in-law and I became my father’s father-in-law. My daughter is my mom and my wife is my granny!
More problems occurred when I had a son. Now my son is my father's brother and so he is my uncle. Situation turned even ticklish when father had a Son. Now my father's son i.e., my brother is my grandson. Ultimately, I have become my own grand father I am my own grandson. And you say you have family problems!!
Duh!! what the duck.. seriously. Reminds me of a hilarious movie I saw on a similar topic: http://www.imdb.com/title/tt0382784/
