Synopsis by Mark Deming
While stuck in traffic following a talent show at Springfield Elementary School, Homer Simpson (voice of Dan Castellaneta) spies a Canyonero, a fully-loaded S.U.V. that can practically roll over slower vehicles, and he decides it just the kind of car he needs. Despite the price, Homer buys one the next day, only to be told by several of his friends this his red F-Series Canyonero is generally regarded as the women's model. Regarding this as a low blow to his masculinity, Homer refuses to drive the S.U.V., and Marge (voice of Julie Kavner) starts using it to run errands. Marge finds she enjoys driving the larger vehicle, but it makes her much more aggressive behind the wheel, and she's soon cited by Police Chief Wiggum (voice of Hank Azaria) for road rage. Marge attends a court-mandated class in anger management, but on the way home she roars through traffic and ends up crashing through a fence at the county jail, allowing the prisoners to escape. Marge's reckless driving causes her to lose her license, but Chief Wiggum finds a use for Marge's aggressive style of driving when a pack of rhinos break loose from the Wild Animal Kingdom park. "Marge Simpson in: 'Screaming Yellow Honkers'" was first aired on February 21, 1999, and features a voice cameo from country music star Hank Williams Jr., who sings the Canyonero jingle.
