In the production of the Season 7 Episode 8 of South Park, "South Park is Gay!", creators Matt and Trey brainstormed the ending for hours, before coming up with a completely goofy out-of-the-blue third act that barely tied into the entertaining initial premise and have since referred to the episode as "one of their worst" due to this random reveal dragging down the entire setup; yet despite that, fans at large seem to have found the ending hilarious and have professed great enjoyment of Crab People.

The last two seconds of Iron Lung are the horror equivalent of Crab People.
