All of Yelp's quotes on this article seem like satire to me "Our company, along with its millions of users, take Yelp very seriously. The South Park episode was in extremely bad taste and not funny whatsoever."
Yelp was tweeting during the episode, they loved the publicity...the lawsuit is a hoax, but just reading the article gave it away...i didn't even make it to the fappy part, they lost me at the fake Snopes lawsuit
