Mocked in: Season 3, Episode 3
You can tell how hip a restaurant is by the length of its Yelp reviews. Your cool friends who are perpetually frustrated with their unfinished novels and screenplays have no trouble penning a 1,000-word Yelp review. These reviews go off to independent coffee store owners and restaurateurs who take them as gospel handed down on tablets. It's enough to make you wish you could write angry Yelp reviews of other people's Yelp reviews.
And that's how the world ends.
