This means living in the apartment building he grew up in, sandwiched between his meddlesome parents and his highly competitive brother, played by David Walton, who happens to be a successful surgeon with an equally successful wife and marriage with a newborn baby.
The series is inspired by star and co-creator Mark Feuerstein’s life, which is where the show’s title comes from. He lived in apartment 9K, while his parents resided in 9J, and his brother, sister-in-law and their baby in 9L.
