King of the Hill

Dale Gribble's father, Bug Gribble, is openly gay and featured in a gay rodeo in the episode "My Own Private Rodeo" (S6E18). Peggy Hill exhibits acceptance towards a gay friend, stating to Bobby, "Oh honey, there was nothing broken about him. He was just gay…. Very… very gay". In "The Peggy Horror Picture Show" (S11E03), Peggy befriends a drag queen named Carolyn (Jaime out of drag), and the episode touches on perceptions of gender presentation and acceptance. Bobby Hill's character often challenges conventional masculinity, leading Hank to sometimes question if "the boy ain't right" due to Bobby's less traditional interests and passive nature.

In "Bobby Goes Nuts" (S6E01), Bobby learns a women's self-defense technique involving groin kicks and repeatedly applies it to various characters, including Hank, as a running gag. In "The Texas Skilsaw Massacre" (S7E07), Hank accidentally cuts off Dale Gribble's finger with a circular saw. While the injury is significant, the finger is later reconnected, and the event is treated with dark humor rather than graphic detail.

Characters are sometimes seen making out or are implied to have engaged in sexual intercourse for comic effect. In the revival (Season 14), an adult Bobby Hill (now 21) is depicted as sexually active, with a scene implying a hookup accidentally overheard by Peggy via a butt-dial. The episode "Ho Yeah!" (S5E13) centers on Hank and Peggy unknowingly housing a prostitute named Tammi, leading to Hank being mistaken for a pimp. Nudity is usually pixelated or private areas are covered, such as in an episode satirizing reality TV, or when Bobby accidentally sees Luanne naked in "Naked Ambition" (S4E15).

The Disney+ content warning explicitly mentions the use of words like "bitch" and "shit". Hank himself is heard using profanity, such as calling someone "bitch ass" in an episode. Boomhauer's distinctive speech pattern often includes mild expletives like "dang ol'". The show's Season 14 revival on Hulu features an increase in cursing, although producers were advised to avoid a TV-MA rating, and Hank typically refrains from strong language.

In "The Witches of East Arlen" (S7E23), Bobby Hill joins a local coven after taking an interest in tarot cards. The coven, led by Ward Rackley, engages in practices like fortune-telling, chanting in 'Canis Latinicus,' and attempts at rituals involving drinking a chalice of dog's blood. The episode displays occult symbolism, such as a Buddha statue and images of dragons/demons in their lair, but ultimately portrays the group's activities as silly and ineffective, with Bobby himself finding them ridiculous.

Bobby Hill often displays a rebellious streak, such as when he repeatedly kicks people in the groin after learning a self-defense move, even kicking Hank in "Bobby Goes Nuts" (S6E01). Peggy Hill is frequently characterized by her arrogance and inflated self-esteem, leading to disrespectful interactions. Examples include her calling Thanksgiving Eve the "busiest travel day of the year" as if it were her own discovery, or humorously hijacking dishes by renaming them "Spah-Peggy and Meatballs". Hank also grapples with disrespect from younger generations, such as in "The Man Who Shot Cane Skretteberg" (S2E07) when he deals with a rude teenage garage band.
