Two men met at a bar and struck up a conversation.
After a while one of them 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 and we got married. Lately, my father married my stepdaughter. That made my stepdaughter my stepmother and my father became my stepson. Also my wife became mother-in-law of her father-in-law.
Then 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 grandson. That made me grandfather of my half-brother. This was nothing until my wife and I had a son.
Now the sister of my son, my mother-in-law is also the grandmother. This makes my father the brother-in-law of my child, whose stepsister 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...
...and you think you have family problems?!"
