Veronica Crabtree

Ms. Veronica Crabtree was South Park Elementary's main bus driver. She was voiced by Mary Kay Bergman during the first three seasons and by Eliza J. Schneider until her death. She was similar to the school bus driver in the 1994 film Forrest Gump, who also had a bird in her hair.

While she has never performed the voice in the series, April Stewart has stated on Twitter that she performed the voice in her audition before Season 8 and is still capable of doing so.

Background
In the episode "Cartman's Mom Is a Dirty Slut", it is implied at the end of the episode that she had sexual intercourse with Liane Cartman, which made her a potential mother of Eric Cartman, but as a result of "201", it is revealed that Liane was Eric's mother.

Crabtree was, for the most part, a background character, used only for the occasional joke or for scenes on the school bus. However, she received a prominent role in "City on the Edge of Forever (Flashbacks)", when upon driving the kids back from school, she takes the bus off the main road and ends up getting it stuck on the edge of a cliff. Crabtree immediately goes to get help for the kids and orders them to stay on the bus in her absence, by threatening to kill a bunny. While the students have assorted flashbacks relating to past adventures, she makes it to the main road and is picked up by a trucker, who slips her roofies in order to date-rape her. However, the drugs only seem to calm her slightly from her normal insanity. She begins a relationship with the trucker, thus forgetting about the kids, and begins life as a stand-up comedian on The Tonight Show With Jay Leno. However, she finds the life empty and goes off with the trucker to watch the sunset. At the end the episode everything, even Crabtree's own story is implied to be a dream of one of the boys, which she and the trucker acknowledge sadly.

In the episode "Fat Camp", Kenny was supposed to crawl into her uterus and stay there for six straight hours before coming out. She was excited about being on TV, adding that she hadn't had this much attention paid to her cooch since she was 16. Later, when Kenny's lookalike, came out of her uterus dead, she said: "I told you I was a tight virgin flower." This is a continuity error - not only are the quotes contradictory, but Ms. Crabtree had sex with Chef in "Chef Aid", albeit with a bag over her own head.

Her final surviving appearance was in "Simpsons Already Did It" driving the bus and surprising Butters in a Simpson-ified form of herself. She only screams a few times, then drives off.

Death
Ms. Crabtree was murdered, as well as the bird nesting on her head, with left hand and wing missing, by Michael Deets in "Cartman's Incredible Gift". The police officers commented "She was considered an ancillary character. One the fans wouldn't miss much." Sergeant Yates also yelled, "She may not have been in any recent episodes, but dammit she deserved better than this!", poking fun at her lack of recent appearances at the time. This also marked one of South Park's few moments of breaking the fourth wall. The school bus driver position was then evidently taken over by Jose Venezuela, as shown in "Ginger Kids".

Appearance
She wore a blue sweater and green trousers. She had crooked yellow teeth, baggy eyes, an angry expression (most of the time), and messy, scraggly brown hair. Her hair has a bird living on it.

Personality
She appeared to be mentally unstable. She constantly screamed at the children on her bus and always asked "What did you say?", after they insulted her. Occasionally, she screamed blindly at the students to intimidate them. In later episodes, she appeared to be slightly calmer and rational.
