In the earlier seasons, Liane was frequently shown giving people of the town of South Park her baking, mostly cookies.

One example of her generosity is seen in "Cartman's Mom is a Dirty Slut", where she gives a plate of cookies to Officer Barbrady at the Drunken Barn Dance.

For example, in "Good Times with Weapons", Eric claimed that he and Liane went to see the movie The Passion of the Christ for an argument proving that Jews are sneaky liars.

In "Cartman's Mom is a Dirty Slut", Dr. Alphonse Mephesto stated that Liane was a hermaphrodite with both male and female sexual organs.

It was also stated that in the events of the episode, years ago at the Drunken Barn Dance, Liane proceeded to have sex with numerous men and women.

[7] The next episode, "201" reveals that Liane is not a hermaphrodite, and the citizens of South Park lied in order to protect the Denver Broncos from a scandal.

[10] Though Eric and Liane share a great bond with each other, in later seasons, she feels stern about his poor actions, which resolves further in later episodes.

The two, along with her son's other friends, who are Stan, Kyle, and Kenny, are in Nebraska to visit Liane's relatives - most of which are similar to Cartman, with the same speech mannerisms, as well as catchphrases such as "Respect Mah Authoritah!"

[18] Liane's relatives are parents Harold and Mabel (who died prior to Cartmanland), brothers Howard, Stinky and Bob, and grandmother Florence.
