Cleo Broflovski

Cleo Broflovski is the deceased mother of Sheila Broflovski, but unusually she shares her daughter's married name. Using this, one may conclude that it was Gerald Broflovski that took Sheila's surname, or simply that both may have had the same last name even before marriage.

So far she has only appeared as a corpse in the third season Halloween special "Korn's Groovy Pirate Ghost Mystery" when the boys dug her up in order to frighten the 5th Graders (who are now the 6th Graders). During the course of the episode a dog ate the corpse, but later regurgitated it to the disgust of everyone at the Halloween festival. This is a parody of a scene in the cult horror-comedy film Braindead, in which a dying old woman regurgitates the body of a dog. Later, the boys managed to frighten the 5th Graders with her.

In the sixth season episode "The Biggest Douche in the Universe" the psychic John Edward "receives a message" from Cleo for Kyle Broflovski stating that he is to look out for four white doves, which he sees at the New York Airport (having traveled there to feature on the show). Kyle sees the four white doves on an advert for a Jewish school named Jewleeard which he joins. After some convincing from Stan Marsh he finally realizes the psychic was just cold reading and returns to town stating that Cleo is "dead and gone forever".

In the episode A Ladder to Heaven when Stan and Kyle reach the clouds they look for heaven and Kyle exclaims, "Grandma?"

In the episode "It's a Jersey Thing" - it is reveled that Sheila had grew up in Newark, and that her parents had lived there whilst pregnant with Harold. It maybe assumed that Cleo might had moved to South Park; like her daughter, to escape from New Jersey.
