The gang's friend Shawn thinks he's cool by carrying around his father's gun. All are impressed except Fat Albert, who goes to his parents in an effort to stop him. Though the gun is usually unloaded, Rudy finds a bullet which enables Shawn to use it for target practice. But a near tragedy occurs when the gun backfires, severely injuring his hand. Fortunately, his father had medical training which helps to save his son. As a result, the gang learns a valuable lesson.
