I had to check to make this article wasn't from The Onion:

The episode at the center of the lawsuit, titled, You’re Not Yelping, parodies Yelp reviewers, going as far as comparing them to ISIS, while also continuing the season-to-date theme which mocks political correctness.
Matt Stone and Trey Parker, creators of the popular animated series, were quick to issue a statement of their own.
“We’ve taken a hard look at the information presented to us, and after reviewing it, we have given Yelp and their lawsuit only one star. Their lawyers delivered us legal documents in a very unprofessional manner; not bothering to smile or even a quick handshake. The writing on the envelope was barely legible and in two different colors. It is our personal opinion that Yelp could do a much better job by not suing us for ten million dollars.”
