A Big Joke

Two men met at a bus stop and struck up a conversation. One of
them kept
complaining of family problems.
Finally, the other man said: "You think you have family problems?
Listen to
my situation."
"A few years ago I met a young widow with a grown-up daughter. We
got
married and got myself a stepdaughter. Later, my father married
my
stepdaughter. That made my stepdaughter, my step-mother. And my
father
became my stepson. Also, my wife became mother-in-law of her
father-in-law."
"Much later the daughter of my wife, my stepmother, had a son.
This boy was
my half-brother because he was my father's son. But he was also
the son of
my wife's daughter which made him my wife's grand-son. That made
me the
grand-father of my half-brother."
"This was nothing until my wife and I had a son. Now the
half-sister of my
son, my stepmother, is also the Grandmother. This makes my father,
the
brother-in-law of my child, whose step-sister is my father's wife,
I am my
stepmother's brother-in-law, my wife is her own child's aunt, my
son is my
father's nephew and I am my OWN GRANDFATHER!"
