The title of this episode is a reference to an earlier episode in the series Season 1's "Sacred Cow."
This is the first episode where comedy partners Keegan-Michael Key and Jordan Peele guest star together despite appearing separately in many episodes.
There was some confusion over this episode's title as Loren Bouchard stated in a January 2016 interview in NJ Tech Reviews that the episode's title is "Second Couch", this might have been a typographical error as the official title was confirmed to be "Sacred Couch" by Fox's official press release.
A total of 2.64 million households watched this episode.
