The episode spoofs the TV show Hoarders, Hoarding: Buried Alive, and the film Inception.
The episode was written and directed by series co-creator Trey Parker, and was rated TV-MA-LV in the United States and MA15+(a) in Australia.
A hoarding specialist named Dr. Chinstrap, as well as the rest of the student body, help Stan go through his locker, which is stuffed with some disgusting items, including a maggot-infested sandwich and broken toothbrush which Stan, who soon loses his composure, refuses to give up, shocking Kyle, Kenny, Cartman, Wendy and the rest of the school.
The dream moves on to the next morning when Stan, Mackey, the sheep hoarder, and the kids board a bus for the field trip.
While Freddy Krueger does not wish to come back, stating that Chinstrap needed him to murder several teenagers in the belief that it would help 'stop the Russians', they convince him to help out a final time.
But when they realize Mackey is not waking up, he remembers what happened, explaining he ran from the bullies and went into a shack, where someone talked nice to him but then touched him in a bad way.
Freddy is beyond remorse because he could not save the sheep herder (ironically the only one who recognizes him correctly as a shepherd).
"[1]Gurewitch has since said that their apology was accepted, and that he and Young plan to "meet up with Matt and Trey when they're in New York.
"[1][2] In its original American broadcast on October 20, 2010, "Insheeption" was seen by 2.891 million viewers according to Nielsen Media Research, making it the most watched cable television show of the night.
[4] IGN gave the episode a score of 7 out of 10 and wrote: "This episode had a great premise, and I did find myself laughing a couple of times (Cartman's few lines in this story are hilarious), but this installment gave me the impression that the creative team weren't really trying that hard.
Maybe the team is distracted by other things, or maybe the debacle with the Mohammed episode took some wind out of their sails, but the spark seems to be missing, and I'm hoping it returns soon.
