Tsst

"Tsst" is the seventh episode of the tenth season of South Park.

Synopsis
Liane cannot control her son anymore, and decides to use the help of reality TV shows to show that Cartman's behavior can be controlled.

Plot
At South Park Elementary, Mr. Mackey has called Ms. Cartman and Cartman to his office to discuss the latter's behavior. Liane bursts into tears after explaining how difficult it is to control her son's behavior. Mr. Mackey recommends a TV show called Nanny 911, which features Deborah Carroll, Yvonne Finnerty, and Stella Reid.

At his house, Cartman is playing on his Xbox 360 when Nanny Stella arrives along with a camera crew. She promptly annoys Cartman by taking away his Xbox, so he gets revenge by bullying her by asking her why she didn't have kids of her own, because she was ugly and how she's getting too old to have kids of her own. Angered and upset, she marches out.

Supernanny works even less, with her ending up in a mental institute feeding on her own feces. Liane asks the surgeon treating Supernanny what else she can do, and he recommends another show; The Dog Whisperer.

When Cesar Millan turns up, he instantly makes an impact on Cartman, who is angered so much he runs away from home.

Looking for a place to stay, Stan, Kyle, Kenny, Butters, Jimmy and Craig turn him down and he is forced to stay in an alleyway in the rain while they play Xbox.

He returns, and is angered to see Cesar Milan is still there. Cartman begins to behave soon and realizes he's changing for the worse (as he sees it). He devises a plan to kill his mother but Stan, Kyle, Kenny and Butters will not help.

That night, Cartman prepares to go ahead with his plan, but suffers a strange experience that convinces him the changes are for the best. When Liane comes down to breakfast, Cartman is going over his homework and eating a healthy meal. Cesar pays a final visit, and Liane asks him if he wants to see Madama Butterfly with her, but he explains she is just a client, and he has other work to be getting on with. Liane is disheartened and invites Cartman, promising to buy him a Mega Ranger, he asks if he could have two and Liane says he can have whatever he wants, returning Cartman to his normal ways...

Trivia

 * The story of Cartman handcuffing Billy Turner's ankle to a flagpole and giving him a hacksaw is taken from the movie "Mad Max", it also makes a reference to the movie "Saw" as he stated that he poisoned his milk.
 * In the mock intro of Nanny 911, there is a nanny named 'Nanny Skexis', from the film The Dark Crystal.
 * The ending mirrors scenes from The Omen.
 * There is a clip from "The Passion of the Jew" in this episode.
 * During the theme song for Super Nanny, you can see a kid behind the nanny the looks like Kenny from the side.
 * Due to the events of Scott Tenorman Must Die, Cartman's evil behavior reached a level difficult to top by writers. As such, the events of this episode appears to be a devise in which to deus ex machina Cartman back to something more like how he was at the start of the series and thus have a more managable level of evil behavior for the writing staff.
