The most famous family in Springfield, and one of the most well-known on all of television, is entering its 21st season on-air this weekend and Fox Licensing will be popping open cans of Duff and ringing in 20 years of The Simpsons accordingly.

New deals, product launches and partners from around the world are joining more than 600 existing licensees and other promo partners on the property’s program.

State-side, Fox Licensing and Mattel have teamed up for The Simpsons Scene It? The DVD Game.

Fox is also expanded agreements with partners in the UK, with Wesco adding mugs, barware, and a Spiderpig money bank to its list of Simpsons products, which already includes water coolers, mini-fridges and clocks. Bath and body care company Baylis & Harding will also be rolling out a line of licensed toiletries, while JJ Valliant will produce high-end resin figures for the territory.

Further across Europe, Big Boss in Italy will release branded PC and console accessories in 2010. Spain’s ProFab is on board for inflatable castles and slides and Segora for perfume.

Over in Latin America, beverage player Watt’s will feature a free on-pack Simpsons sticker with every participating product. The promo will included flavored milk, juices, drinkable yogurt and milkshakes.

Canuck agent Segal Licensing, meanwhile, inked a deal with KFC Canada for a Can We Eat Yet? celebration on September 7 for six weeks, which will see a free Simpsons figurine with the purchase of a Family Bucket Meal. Families can also enter a national sweepstakes for a family trip to the Simpsons Ride at Universal Studios, Hollywood.

Down under, News Limited newspapers will also be celebrating the anniversary, providing readers with popular collectible Stick’ems and albums during the promo period.
