Born from The Simpsons episode “Lemon of Troy,” The Dud began as a harmless joke — Milhouse’s rock that bounces instead of exploding, followed by his defeated line: “It’s a dud.” But online, it became something else. A strange, contagious meme — people who see him start mimicking that eerie Homer smile, a warped grin of failure and false confidence. Now, The Dud has grown into a full-blown internet cult. Viral clips show characters getting “infected,” their faces twisting into that same grin. No one’s sure if it’s a joke anymore.
