Mary Cooper discovers that Sheldon was not invited to Billy Sparks' birthday party. Concerned about his social isolation, she involves Pastor Jeff to pressure the Sparks family into inviting him. Sheldon eventually attends but insists on a strict "contract" for his participation, including only mouthing the words to "Happy Birthday" and eating exactly one slice of cake.
