It's actually a "Family Matters" reference. See, at the beginning of the show, the Winslow family featured a husband (Carl), a wife (Hariette), and their three children (Laura, Judy, and Eddie). Ultimately, Judy got cut out from the show around the middle of the series because of budget reasons. Afterwards, she was never brought up again and the show acted like Laura and Eddie were the only Winslow children.
