Beth is a student at Pearl Bailey High School.
In "Escape from Pearl Bailey", Beth is seen at the school election.
Beth appears in "Daddy Queerest" in the school gym, where she is shocked by the fact that anyone can get drunk and make out with a girl like Jewel. After this horrifying story of how Steve Smith did just that, she is seen running out of the gym, throwing a beer bottle into a recycling bin.
In "Brains, Brains and Automobiles", when Steve, Snot, Toshi, and Barry wear thongs to their camp, the boys in the camp get angry and hurl them over to the girl's side of the camp. Beth is in the girl camp.
Beth also appears in "License to Till", where she is shown walking down the school hallway, when she suddenly sees Steve's fake wiener and is surprised by it.
She and Melissa are friends with Roger's persona of Bing Cooper, a sexually-active high school student in "I Am the Walrus". Beth confronts him when she finds an acceptance letter to UCLA, believing they were going to Arizona State University together. Roger admits that he only wished that she found out when he didn't show up at Arizona State. Beth is voiced by Janna Levinstein.
She can be seen in the audience of the talent show in "The Talented Mr. Dingleberry".
