Other Boomhauers
- Patch Boomhauer (voiced by Brad Pitt) — Patch is Boomhauer's sleazy, womanizing younger brother. He appears in "Patch Boomhauer", apparently engaged to marry Boomhauer's old flame, Katherine - much to Boomhauer's mounting displeasure, as he himself has unresolved feelings for Katherine, and Patch's continued philandering angers him for her sake. The wedding is later called off after Patch hires strippers for his bachelor party and frames Boomhauer for trying to break up the engagement. Patch makes a final cameo in "Lucky's Wedding Suit" as one of the guests at Luanne and Lucky's wedding. Patch, like Boomhauer, speaks in a fast-paced Southern gibberish.
- Dr. and Mrs. Boomhauer (voiced by Mike Judge) - Boomhauer's parents. Mrs. Boomhauer is shown to speak like Boomhauer in "Peggy's Turtle Song". In "Three Coaches and a Bobby", Boomhauer mentions that his parents had won the lottery and moved to Florida.
- "Mee-Maw" Boomhauer (voiced by Mike Judge) - Boomhauer's elderly grandmother. She is only seen once, in "Dang Ol' Love", when Boomhauer, infatuated with Marlene, goes to Mee-Maw to ask for a family-heirloom wedding ring. Mee-Maw speaks in the same characteristic gibberish that the rest of the Boomhauers share.
