Cartman is shown to be left-handed in this episode.

Cartman chained Billy Turner's ankle to a flag pole, poisoned his lunch milk, gave him a hacksaw, and told him that the only way he could reach the antidote in time would be to cut through his ankle. This a reference to the Mel Gibson film, Mad Max.
The one of the paintings at Nanny Central is Leonardo da Vinci's "Lady With An Ermine".
Cartman hums Journey's "Don't Stop Believing".
After Cartman is leaving his mother's room, he stumbles around the hallway and appears to take on different physical appearances. The transformations closely resemble the final scene in Ken Russell's Altered States. A dead giveaway to this reference is both Cartman and Dr. Jessup appear to have complexions that sporadically change to something that resembles the static from a TV without a signal.
At the end of the episode, the camera slowly zooming into Cartman's smiling face while the song Ave Satani starts playing is a reference to The Omen. It could also be a reference to the horror film Friday the 13th: The Final Chapter.
One of the Nannies shown is a "Skeksis" from The Dark Crystal.
When Cartman asks Stan to shoot Liane in the face, Stan asks "Where am I supposed to get a gun?". Considering that his uncle Jimbo runs the gun shop and hasn't had any problem getting the boys some firepower in the past, this wouldn't actually be too difficult.
Jimmy asking Cartman, "What's my last name?" and Cartman not knowing is possibly a reference to his inconsistent last name. "Krazy Kripples" had given Jimmy's last name as Swanson, however, "Up the Down Steroid" had established it as Valmer. Later episodes confirmed his name as Jimmy Valmer.
