Nominated for the outstanding animated program category of the 67th Annual Primetime Emmy Awards, "South Park" will be up against "Archer," "Bob's Burgers," "Over The Garden Wall" and "The Simpsons."

In particular, the Comedy Central adult animated comedy series was nominated for "South Park" season 18 episode 5 titled "Freemium Isn't Free," which aired on Nov. 5, 2014. In the episode, an effort to help make money to build Canada is made by creating a phone app that hunts the addiction of the weak.

In "South Park" season 18 episode 6 titled "Freemium Isn't Free," Randy Marsh intervenes when he finds out that Stan Marsh has an addiction. Kyle Broflovski also proposes to spread the word about the phone app that preys on the addiction of the weak.

"We have to find a way to get the word out," Kyle Broflovski tells Eric Cartman. "People need to know pushers are being hired to take advantage of people with addiction problems. There has to be a way we can get to the news company and sneak in and somehow borrow their TV signal."

In addition, Kyle Broflovski suggests they should disguise themselves as something ridiculous. Eric Cartman reveals that he tweeted about pushers hired by Phillip and Terrance to make money off addicts and it is trending.

Also in "South Park" season 18 episode, Prince of Canada explains that the "mium" in "freemium" is Latin for "not really."

Parker voiced Stan Marsh, Randy Marsh, Prince of Canada and Phillip while Matt Stone voiced Kyle Broflovski and Terrance.

Winners of the 67th Annual Primetime Emmy Awards will be announced on Sept. 20 on Fox.
