When Reagan (Christina Applegate) and Chris (Will Arnett) finally have their baby, Chris chooses to leave his high-powered law firm to be a full-time stay-at-home daddy. For most sitcoms this would  be an excuse to create a clutzy, borderline-idiotic father figure who ends up washing the baby in the dishwasher for yuks. But Chris is the rare sitcom father who is actually believable. He's not perfect, he makes mistakes, but he truly is trying to raise his daughter and keep his marriage strong at the same time.
