Bobby takes up a new interest in environmental issues, provoked by a new teacher. When the cause rallies to drain the quarry, and rid it of all waste, Hank is dead set against it. Years earlier, while in high school, the gang wrecked Boomhauer's car, and pushed it into the quarry, pleading ignorance. Bobby finds out, and lets Boomhauer in on the secret, just as the guys pull out his Mustang 'Ms. Sally'.

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.
