A scene in the episode shows Grampa and Bart driving to Branson with Marge's car, listening to the radio. Because the scene consists entirely of auditive gags, the "Simpsons" staff had difficulty figuring out what to show visually during the scene. In the DVD audio commentary for the episode, Jean explained that these scenes “get a really big laugh at the table,” but are subsequently hard for the animators. The scene makes use of a repeated background, an animation technique made famous by Hanna-Barbera in order to cut budget.
