According to The Simpsons creator Matt Groening, Marge Simpson's towering 'do was originally supposed to hide a set of rabbit ears. Yes, you read that correctly, rabbit ears. Don't worry, the video below will explain.
For the final episode of The Simpsons, Groening planned on revealing the secret beneath Marge's hair. However, his fellow writers and producers felt this plot twist made little sense for the character.
Even though the rabbit ears have never made it to the TV series (thus far), Groening found other ways to slip these clandestine appendages into various Simpsons properties. Just check out the famous Simpsons arcade game to get an idea.
Though Marge never got her big reveal as a human/hare hybrid, she still managed to make her way into bunny history. In 2009, Marge Simpson became the first animated character to appear in Playboy magazine.
