Limited edition bags of South Park’s Cheesy Poofs will soon be flying off the shelves of Wal-Mart retailers nationwide.

To celebrate the 15th anniversary of the Comedy Central hit, Cartman’s favorite snack is hitting shelves in the real world. That’s right — this fall, 1.5 million packages of Cheesy Poofs, produced by Frito-Lay, will be introduced to shoppers of America’s largest discount retailer at the price of $2.99 a bag.

This isn’t the first time TV fans have been on the receiving end of some seriously cool cartoon-to-real-world crossover promotions. When The Simpsons Movie was released back in 2007, 7-Eleven stores were temporarily converted into Kwik-E-Marts. As if that wasn’t cool enough, they also sold Frosted KrustyOs and Buzz Cola.

Cheesy Poofs are just the beginning.

South Park Digital Studios will honor the fans that have turned the Emmy and Peabody Award-winning series into a cultural phenomenon with a year-long celebration, the network said this month, marking 2011 as “The Year of the Fan.”

“What better way to celebrate 15 amazing years of ‘South Park,’ than by honoring the viewers that have made the iconic series such a long-running success,” says Michele Ganeless, President of Comedy Central. “These all-encompassing ‘South Park’ events will take the fans even deeper into the show, allowing them to experience it in every arena.”

South Park airs Wednesdays @ 10 PM ET/PT.
