Season six of the animated redneck sitcom King of the Hill begins as 13-year-old Bobby Hill, unable to enroll in the Arlen YMCA's boxing class, takes the next available slot in a women's self-defense class, convincing his macho dad Hank all the more that Bobby "ain't right." In other episodes, Hank's substitute-teacher-spouse Peggy takes her students on a field trip to Mexico and ends up being arrested for kidnapping; a carpenter with the initials J.C. performs a miracle during the Christmas episode; the incomprehensible Boomhauer gives Bobby advice on how to handle women, but proves even more tongue-tied than usual when he himself falls in love for the first time in his life; Peggy foments a feminist rebellion at a Renaissance fair; Hank wins the privilege of carrying the Olympic torch through his neighborhood; military-post barber Bill Dauterive steals a tank when he finds out the Army has been using him for a guinea pig; still unaware that Native American John Redcorn is the real father of his son Joseph, conspiracy theorist Dale Gribble becomes convinced that Joseph is actually a space alien; Hank becomes the token white at an all-Asian country club; and the Hills' niece Luanne joins a Stepford-like sorority. In the season's two-part finale, the Hills head to Japan so that Hank's war veteran dad Cotton can make amends to the wife of a soldier that he killed -- and Hank discovers that he has a Japanese half-brother! Guest voices heard during King of the Hill's sixth season include Gary Busey, Bruce Jenner, Laura Dern, Alan Rickman, Charlie Daniels, Vince Gill, Jeff Goldblum, Ed Asner, Megan Mullally, Laura Linney, and Keith Carradine.
