Dennis Henry Burkley was an American actor. In a career spanning four decades, he appeared in numerous films and television series. He is best known for his role as Principal Carl Moss in King of the Hill.

King of the Hill is an American animated sitcom created by Mike Judge and Greg Daniels that initially aired on Fox from January 12, 1997, to September 13, 2009, with four more episodes airing in syndication from May 3 to 6, 2010. The series centers on the Hills, an American family in the fictional city of Arlen, Texas, as well as their neighbors, co-workers, relatives, classmates, friends, and acquaintances. Series protagonist, patriarch, and everyman Hank Hill works as assistant manager at Strickland Propane. He lives in a ranch-style house with his wife Peggy, his son Bobby, his niece Luanne, and his pet bloodhound Ladybird. Hank's neighbors are his longtime friends Bill Dauterive, a divorced, bald, overweight military barber and former high school football star; Dale Gribble, a paranoid, pro-gun, anti-government pest exterminator; and Jeff Boomhauer, a charismatic, soft-spoken, often unintelligible bachelor whose occupation is revealed in the final episode of the series. The show's realistic approach seeks humor in the conventional and mundane aspects of everyday life, such as blue-collar workers, substitute teachers, and the trials of puberty.
