The third season of American Dad! first aired on the Fox Network in nineteen episodes from September 10, 2006, to May 20, 2007, before being included in two DVD box sets and in syndication. The series focuses on the eccentric upper middle class Smith family in a fictionalized version of Langley, Virginia and their six housemates: Father, husband, CIA agent, and Republican, Stan; his wife and housewife, Francine; their liberal, hippie, college-aged daughter, Hayley; their dorky high-school-aged son, Steve; the family's unusual goldfish, Klaus; and flamboyant, master of disguise alien, Roger.
