"Tell me, with your own words what, exactly, is the source of this anxiousness of yours, if you can", told the psychiatrist to his patient.
"Well, it all began when I got married. My wife had a grown-up daughter who, thus, became my step-daughter. Then my father came to visit and congratulate me on behalf of my wedding. He fell in love with my step-daughter and later they married too. Hence, my step-daughter became my step-mother. My wife had a son who automatically became my father's brother-in-law, because he is the step-brother of the
step-daughter married to my father. Since the boy is the brother of my step-mother, he is also my uncle. My father's wife also had a son who is my brother eventhough, at the same time, I am his grand-father - he is the son of my step-daughter, after all. My wife is my grand-mother, the mother of my step-mother. From this it follows that I am the grand-son of my own wife. Taking into consideration that I am married to my grand-mother, I am not only the husband and grand-son of my wife but, I am also my own grand-father."
"That's what makes me anxious."
This joke is not originally mine but, I took the liberty to translate and slightly edit it.
