The 250th milestone episode, "Serves Me Right for Giving General George S. Patton the Bathroom Key," takes place a year after the death of Hank's father, Cotton Hill. In the episode, Cotton's widow, Didi (Ashley Gardner), delivers Hank (Mike Judge) a box full of his father's prized possessions including one last crazy Cotton request to have his ashes flushed down a toilet located in an old bar and once used by General George S. Patton. When Hank enlists Bill (Stephen Root) and Dale's (Johnny Hardwick) help in his "flushing Cotton" mission, the guys' bickering gets them kicked out of the bar. When Hank snaps, his friends come together to help him fulfill his father's final wish.
