Trivia: The horse heart that Daenerys eats was actually made of gelatin, and genuinely tasted dreadful - her physical revulsion at eating it is real. It had dyed pasta to simulate veins, and was injected with fake sugary blood, which attracted flies. The blood was so sticky and ended up covering Emilia Clarke to such an extent that after filming it glued her to the toilet seat.
Trivia: In the opening intro the store next to Bob's is called "Pro-pain Accessories" and the exterminator is "Dale's Dead-Bug." Hank Hill, from the show "King of the Hill", sells propane and propane accessories and his neighbor, Dale Gribble, owns Dale's Dead-Bug. Jim Dauterive, one of the show's creator/writer was also a writer/producer for "King of the Hill."
Trivia: They pay homage to the original 1932 movie Freaks. In Freaks, Cleopatra gets mutilated and turned into a tarred and feathered bird for visitors to gawk at in terror. Hercules gets viciously attacked under the carnival vehicle. In this episode, Stanley gets cornered by all the freaks under the carnival vehicle and gets viciously attacked and mutilated to resemble Meep (a feathered freak who was killed by the cops in an earlier episode).
Trivia: When the feminist group are hiking, the man who stops Toni and Candace and says "you're heading into beaver territory" is Danny Bruno. Bruno plays a beaver-like creature on the show Grimm. Later the tour guide says the forest the Beavers live in is called "Grimwood."
Trivia: The wording on Gavin's orange satchel reads FIRE HARDON instead of FIRE WARDEN. The words appear professionally printed and there is no explanation in the plot as to why this should be. Possibly an 'in joke' or a plot-line that was abandoned in production. (00:12:00)
