The Grim Adventures of Billy and Mandy (2001)

S6E2 Hill Billy

After Mandy and Grim encourage Billy to stop binge-watching TV and chase his aspirations, he dons a chicken costume and sets his sights on becoming a renowned "chicken juggler." Despite his mother's urging to consider a career as a chiropractor, Billy flees to Uncle Chokey's farm to pursue his passion. There, the duo juggles chickens in sync with an antique phonograph, transforming the farm into a whimsical 1920s black-and-white cartoon. Meanwhile, Mandy and Grim, investigating a citywide egg shortage, arrive at the farm and inadvertently destroy the phonograph, restoring everything to its usual state.
