"Oh, so the world's biggest asshole has the world's smallest dick?"
- Doreen expressing her disgust for Chuck
Doreen is an employee at Sawitzki and Son's electronics store.
Doreen is often hit on by her boss, Chuck Sawitzki, much to her annoyance.
In the episode "The Bleedin' in Sweden", Chuck hits on Doreen and tells her what a large dick he has. Even later saying that he was rejected from the army because it was too big. He kept saying nonsensical stuff about himself to the point where Doreen got annoyed. When Chuck was hitting on her right at her face, she said "Did a bomb shit in your mouth?" Her quip made Chuck self conscious about his breath, because right after she said that, Chuck pulled back to check his breath.
In "O Holy Moly Night", Chuck tells her that he's late for being measured by the people from Guinness Book of World Records, to which she quips back "Oh, so the world's biggest asshole has the world's smallest dick?" It‘s pretty clear that she hates Chuck for his obnoxious behavior.
She appears to be a law student, based on the book she is reading in "The Bleedin' in Sweden"
