A physician visited a California mental institution and asked a patient How did you get here? What is the nature of your illness?

He got this reply.

It started when I got married and I guess I should never have done it. I got hitched to a widow with a grown daughter who then became my stepdaughter.

My Daddy came to visit us, fell in love with my lovely stepdaughter, then married her. And so my stepdaughter was now my stepmother.

Soon my wife had a son who was, of course, my daddys brother-in-law since he is the half-brother of my stepdaughter, who is now, of course, my daddys wife. So as I told you, when stepdaughter married my daddy, she was at once, my stepmother. Now since my new son is brother to my stepmother, he also became my uncle.

As you know, my wife is my step-grandmother since she is my stepmothers mother. (Dont forget that my stepmother is my stepdaughter.) Remember, too, that I am my wifes grandson.

But hold on just a few minutes more. you see, since Im married to my stepgrandmother, I am not only the wifes grandson and her hubby, but I am also my own grandfather.

Now can you understand how I got put in this place?
