Hank fails to install the new valve on the water heater correctly, and it causes a leak, leaving Peggy to wake up with Bill hovering over her on the front lawn. Not wanting any further complications, Peggy hires Mack, an African American repairman. Ladybird attacks Mack, and he accuses her of being a racist dog and quits. When a dog trainer tells him that Ladybird subconsciously follows Hank's lead, everyone accuses Hank of being racist, too.

King of the Hill is another animation hit from Beavis and Butthead creator Mike Judge, who also voices the starring character Hank Hill, a propane gas salesman in the fictional town Arlen, Texas. Hank is often besieged by the idiosyncrasies of society, but he finds (some) serenity in his home-life with his wife, substitute Spanish teacher Peggy, his awkward son Bobby and his live-in niece-in-law Luanne Platter. Adding flavor to the ordinary dish the series serves are Hank's friends, divorcee military barber Bill Dauterive, paranoid Dale Gribble (with an obsession with Government conspiracy theories) and gibberish spouting Boomhauer.
