Parks and Recreation star Lucy Lawless discusses the possibility of her character, Diane Swanson, having trouble with her husband Ron. Played by Nick Offerman, Ron is a deadpan, stoic character in the beloved sitcom. Rons inclination towards alone time and no-nonsense is constantly in play and draws him towards eccentric women who usually go by the name Tammy. This changes when he meets Diane, a middle school vice principal who is no stranger to madness. They start a relationship in season 5 and later marry.
