Sam was experimenting growing string beans, but his crop turned out very poorly. Sam consults with his friend Ralph Barton, but Ralph has no answers. He then talks to Harry at the lawn and garden shop in town, but he's no help. Meanwhile, Millie is growing string beans in her backyard garden. Sam later sees Millie's beans and asks her what she did to get them to grow so well. Turns out Millie did nothing special but water them.

"The Carolina Pen and Quill", the state literary magazine, sends a letter to Howard. The magazine is initiating a new poetry section for native North Carolina poets. They would like to commission him to write an original poem for the page. Some time passes and everyone is wondering how Howard's poem is coming along. The reality of it is that Howard is suffering from writer's block. Sam comes by Howard's office and reminds him of the deadline for the poem. Now his writer's block gets even worse. After hearing that he isn't eating, Aunt Bee brings Howard some food. But her being around is distracting Howard. Howard's friends start to realize the pressure he is under. Howard goes out to the woods to get some inspiration. Goober comes by and tries to give Howard a pep talk, but Howard just wants him to leave. Later, Howard believes he's a failure and tells this to Sam. Howard winds up writing a poem about failure and it gets published.

Howard complains to Sam about the lack of new residents and wants to hold a special city council meeting concerning Goober. The council says that Goober is going to sheriff's academy two nights a month and worked under Andy. The men vote down Howard's motion to hire a sheriff. Emmett inadvertently tells Goober about the meeting and Goober is now upset. Howard comes up with a plan to stage a bank robbery. He wears a stocking to disguise his face and uses a water gun to hold up the teller, Hilda, and leaves with a bag of money. Howard gets into his car but it won't start. As Goober comes over to talk to Howard, Hilda comes out and points out Howard as the robber. Goober arrests Howard and many of the townsfolk see Goober take Howard to jail. From his jail cell, Howard tries to explain himself to Goober and the two start to argue. Sam holds another council meeting at the court house. At the meeting, Sam uses some psychology to get Goober and Howard to be friends again.

Goober receives a letter from his older brother Braden that he is returning to his hometown for a visit. Braden joined the Navy nearly 20 years ago and stayed in California. Goober believes he works in a factory and probably had to save up for this trip. He hopes Braden will be impressed with the fact that he owns his own gas station. In reality, Braden is a successful and important engineer in the government's space program. Goober arranges a dinner party for when Braden arrives. When Braden sees Goobers room, he decides to not tell Goober about his job. At dinner Braden receives an call from his job and the men discover he's an engineer. The waitress says that he also has calls from Washington D.C. and NASA. Sam then remembers reading about Braden and the space program. This makes Goober feel inferior, and something Emmett says makes Goober feel even worse.
