The 'Moe Tossing Barney Out' meme originates from a Season 4 episode of The Simpsons titled 'Homer’s New Diamond.' In the scene, Moe Szyslak physically ejects a drunk Barney Gumble from the tavern, only for Barney to miraculously reappear behind Moe's shoulder seconds later. This two-panel sequence has become the definitive internet template for representing things that won't stay away, such as persistent bugs in code, bad habits that resurface, or recurring responsibilities. It perfectly illustrates the frustration of solving a problem only to have it immediately return in the exact same spot, often with zero explanation for its persistence.
