"King of the Hill" is set in the fictional small town of Arlen, Texas. The show centers around the Hill family, headed by the ever-responsible, hard-working, loyal, disciplined, and honest propane salesman Hank Hill (voiced by Mike Judge). The punning title refers to Hank as the head of the family as well as metaphorically to the children's game King of the Hill. Hank is employed as the assistant manager at Strickland Propane, selling "propane and propane accessories", a frequent catchphrase. He often finds his traditional conservative values challenged by the changing world around him, though his common decency always sees him through. Hank typically serves as the "de facto" leader for his friends and family. His wife Peggy Hill (née Platter) (voiced by Kathy Najimy), a native of Montana, is a substitute Spanish teacher, though she has a poor grasp of the language. Peggy also finds employment and avocation as a freelance newspaper columnist for "The Arlen Bystander" as well as a Boggle champion, a notary public, a softball pitcher, and a real estate agent. She is confident, sometimes to the point of lacking self-awareness. Hank and Peggy's only child, Bobby Hill (voiced by Pamela Adlon), is a student at Tom Landry Middle School. His characteristic lack of athleticism and interests in prop comedy and cooking are mystifying to his more conventional father but are encouraged by his mother.
