My Two Dads is an American sitcom that starred Staci Keanan, Paul Reiser and Greg Evigan. It aired on NBC from 1987 to 1990.
The show begins when Marcy Bradford ( Emma Samms) in flashbacks, the mother of Nicole Bradford (Keanan), dies. The two men who had competed for the woman's affections--Michael Taylor (Reiser) and Joey Harris (Evigan) before Nicole was born had been awarded joint custody. The mix-ups of two single straight men raising a teenaged daughter provided the story each week.
Nicole's actual paternity was never revealed on the show. However, in one episode, Nicole had a DNA test run to determine which of her two dads was her biological father. She destroyed the results before opening them after realizing that she was happier not knowing who the father was. Margaret would later look at the results, but threw them away afterwards and didn't reveal the results.
