Background[]
Liane Cartman hires Jo Frost from Supernanny to help improve her son's behavior. Jo shows up to the Cartman Residence, but three days later, she is shown to have failed and what Cartman did to her lead her to be sent to the Slater-Carey Mental hospital, where she is shown sobbing and eating her own excrement from a toilet. Between mouthfuls of defecate, she screams that Cartman comes from Hell. Liane is horrified, but is advised by the doctor that she could hire Cesar Millan, who is eventually successful in improving Cartman's behavior.
