Mike takes the child in and confronts the townsfolk, who reluctantly admit to knowing the boy’s mother was one of Hank’s whores. When she died they sent Zack to Mrs. Johnson because he was ””simple.”” Mike is frustrated in her attempts to find a medical diagnosis and cure for Zack’s condition.

Meanwhile, Brian seems to be the only one to get the boy to exhibit his artistic abilities, and he is mistakenly given credit for a drawing that Zack has done. Later, when Zack’s artistic talent is discovered, Hank agrees to send him to an art school in Denver. The show has a cute opening scene of Mike and Sully with him criticizing her driving.
