A: Rome not only had the first apartments, but also the first landlords. Roman law prohibited cohabitation between a man and a women, unless the man was homosexual.
Often times, a young man, down on his luck, hoping to make it as a chef, would pretend to be homosexual in order to live cheaply with two young women. He would have to carry on the charade whenever in the landlord's presence, but was actually something of a ladies' man, creating hilarious misunderstandings week after week.
Years later, after the the Fall of the Roman Empire, a television show was created, based on life in a Roman apartment complex.
That show was ALF.
Obviously, they changed a lot of the details. That's Hollywood for you.
