Muster up your best “Doh!” in preparation for a celebration for the most-watched U.S. television program and the longest scripted show in television history—aka The Simpsons.

To mark the record-breaking 500th episode, to air in February, Twentieth Century Fox Consumer Products is throwing a yearlong celebration. This will include specially tailored brand initiatives created to appeal to the franchise’s wide fan base, a new global retail partnership, and a worldwide QSR campaign with Burger King Corp.

The commemoration starts in September and will continue throughout the show’s upcoming 23rd season. Fox Consumer Products’ new launches will include a “Ladies of Springfield” brand for fashion-forward female fans. The accessories will feature Marge and her two sisters, Patty and Selma. There also will be numerous products based on Duff Beer for male fans.

Bart fans will want to check out the all-new “Bart Sports” line. Bart Sports features Bart-inspired sports gear. “Team Simpsons,” inspired by the upcoming Olympic games in London, aims to bring fans of all ages together as the family celebrates the games of summer in true Simpsons style.

“I Heart Maggie” is the first-ever Simpsons marketing initiative that is directed towards tween and teen girls. The line features Maggie Simpson in an all-new stylized design.

Leading up to the historic 500th episode, Fox Consumer Products has also developed a global direct-to-retail partnership with fashion store H&M. H&M will carry branded apparel and accessories.

In September, Burger King will team up with Fox for a global promotion that will offer 10 “Treehouse of Horror”-themed collectible premiums at participating restaurants worldwide.
