The woman in charge of keeping Seattle Grace's interns in line is Dr. Miranda Bailey, played to perfection by Chandra Wilson. Dr. Bailey—nicknamed "The Nazi"—is known as the resident that you don't want to cross...as her interns found out early on in the first season.
Chandra tells Oprah that the best part about playing Miranda is getting to "holler" at people and getting away with it. "They can't do anything about it, you know? There are no repercussions, whatsoever," she says.
Although Chandra isn't at all like Miranda in real life, she says she draws inspiration from her own mother, the family's disciplinarian, and teachers. "Most of it is really kind of a teacher mentality," she says. "What I try to always say [is], 'Once I have control of the classroom, then I can get something done.' Obviously I don't have control of the classroom."
