Show synopsis
The show begins when Marcy Bradford (Emma Samms), the mother of Nicole Bradford (Keanan), dies. The two men who had competed for the woman's affections before Nicole was born — Michael Taylor (Reiser) and Joey Harris (Evigan) — are awarded joint custody of Nicole. The mix-ups of two single men raising a teenage daughter provided the story each week. Judge Margaret W. Wilbur (Florence Stanley), a family court judge, would frequently visit the new family and served as Nicole's mentor.
Nicole's actual paternity was never revealed on the show. However, in the episode "Pop, the Question", Michael and Joey — after they had a falling out — had a DNA test run to determine which of them was Nicole's biological father. However, the test was conducted against Nicole's wishes, so she destroyed the results before opening them since she was happier not knowing who the father was. Michael and Joey later resolve their differences and reconcile. Judge Wilbur looks at the results, but throws them away without revealing them to the audience.
