Over the past 20 years Southpark has not shied away from poking fun at celebs (Kanye West), Political hot buttons, and now....other animated shows.
In the latest season premiere South Park's episode was titled "A Problem with a Poo" which was a tip of the cap to the "The Problem with Apu" documentary that blasted the Simpsons for being racist and stereotyping different races.
So last night in the episode, Mr. Hankey was forced to leave South Park after saying so many offensive things to people in the town. That is when South Park fired their shot to the Simpsons.
Smart money is on the Simpsons firing back any day now.
