When Sheldon is bullied by an unlikely character Mary and George disagree on how to handle the situation.

While Mary’s away, George finds himself giving advice on Missy’s love life. Meanwhile, Sheldon and Dr. Linkletter struggle to solve an equation; and Georgie has a solution for Meemaw’s business woes.

After graduating high school, Sheldon has a breakdown when he realizes he may not be ready for college. Also, Dale (recurring guest star CRAIG T. NELSON) tries to make amends with Meemaw in the season four premiere episode.

While college orientation does not go as Sheldon planned, Mary is mistaken for a university student and invited to a party. Meanwhile, George helps Pastor Jeff (series regular MATT HOBBY) set up a children’s nursery.

In the season premiere episode Sheldon dismantles the refrigerator to stop an annoying hum; and then must get a paper route to pay for the repairs.

A worried Mary sends Sheldon to Sunday school after she finds him playing Dungeons & Dragons with Tam and Billy; but Sheldon is inspired to study a variety of religions.
