Yvonne Streibel is the art teacher at South Park Elementary. She first appeared in the Season Seven episode, "Toilet Paper". She put Kenny McCormick, Stan Marsh, Kyle Broflovski and Eric Cartman in detention for modeling a penis out of clay instead of doing their schoolwork. The boys then proceeded to take revenge on her by covering her house and lawn with toilet paper, commonly known as TP'ing. Her family was in the house as well and Kyle had doubts about attacking her house because of her twin girls. They continue to anyway and Officer Barbrady comes around the next morning and makes a big deal about it despite Mr. Streibel's efforts to get him to stop.
She then appeared in "Fat Butt and Pancake Head", when she sees Jennifer Lopez. She made a brief appearance in the playground in "All About Mormons". She made her most recent appearance in "Butt Out", where she was running out of the burning school.
She has brown hair with a ponytail, has wrinkles under her eyes and wears a navy blue sweater with a white shirt inside and a maroon skirt. She also wears an apron. She is married and has twin daughters.
