Editing Karen McCormick (section)

==Behind the Scenes==
The original script for "[[Starvin' Marvin]]" referenced a daughter appearing with the McCormick family but she never appeared in the finished episode. According to the South Park Scriptorium, a press image was released of Kenny and his sister by Comedy Central around this time. Nonetheless, the character made no official appearance until "[[Best Friends Forever]]", where she had no lines and was not acknowledged.

She was not referenced or seen again until season 15's "[[The Poor Kid]]", where she made her proper debut, played by Celeste Javier. The name '''Karen''' first appeared on-screen here, but had been commonly used in fan circles for years, having been falsely attributed to Matt Stone by a Wikipedia editor years before. It's inclusion in the episode is therefore likely a nod to South Park fans.

It is believed that Karen and her bond with her brother Kenny was inspired by Nadya and her robot friend Kenny from Protecto 5000, a short from Nickelodeon's Oh Yeah! Cartoons. The short was about a robot named Kenny (voiced by Richard Moll) who befriends a lonely girl named Nadya and protects her from harm. It is also noted that both girl's protectors are named Kenny. Like Karen, Nadya has trouble fitting in, gets picked on by bullies, and hardly has any friends. A connection of South Park to the short is that South Park's Mary Kay Bergman voiced a character or two in Protecto 5000.
