references to popular American reality television programs. Of the most prominent, shows such as Nanny 911 and Supernanny which are both British programs in origin are parodied extensively. Both TV show hosts Stella Reid and Jo Frost are portrayed having accentuated British accents and stereotypically bad teeth. While he reconnects his console with the TV, Cartman sings "Don't Stop Believin'" by Journey. Unlike the "real" television shows, neither Stella's or Jo's methods of disciplining unruly children work - ultimately forcing an insulted Stella to refuse to work with Cartman, and Jo Frost being admitted to a psychiatric hospital, eating her own excrement and repeating the phrase "It's from Hell!" The Dog Whisperer is also featured in the episode, along with show host Cesar Millan, who, unlike most celebrities that were portrayed on the show, is shown in a more positive light. A Skeksis from The Dark Crystal can be seen as one of the nannies. The visual effect of Cartman's angel and devil subconsciousnesses during the part where he almost attempts to kill his mother in her room was a similar reference to the 1997 science-fiction film Contact. The way Cartman changes as he makes his way down the hallway is a direct reference to the 1980 body horror film Altered States. As the episode ends, the closing shot of Cartman staring towards the viewer is a reference to the closing shot of The Omen (1976). Home media "Tsst", along with the thirteen other episodes from South Parks tenth season, was released on a three-disc DVD set in the United States on August 21, 2007.
