(J) Confusing Joke!

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's 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 !!
