S4E16: Duffless

In the episode titled "Duffless," Homer Simpson faces the consequences of his excessive beer drinking after a failed attempt to win a science fair with Lisa. His license is revoked following a DUI arrest, and he is forced to attend alcohol awareness classes. Marge asks Homer to give up beer for a month, and he reluctantly agrees. Meanwhile, Lisa's science fair project involves testing whether her brother Bart or a hamster is smarter, using various tasks to measure intelligence. Unsurprisingly, the hamster outperforms Bart in completing the tasks, leading to her winning the science fair. Homer struggles with sobriety but finds new ways to occupy his time, such as spending quality time with Marge. By the end of the episode, he decides to embrace a healthier lifestyle, at least momentarily, choosing to ride his bike home with Marge instead of driving to Moe's Tavern. It's a small victory for Homer, and Marge seems pleased, suggesting maybe there's hope for him yet—until next episode, anyway.
