@ Young Ismael: Yeah, I know. Miranda had all the qualities to perform well that job, maybe they wanted her to focus on the Denny Duquette Memorial. And they also wanted her to not be so uptight. She was so sure she'd get the job that she didn't.
I don't know if you've heard, but the reason why they got the actor who played Burke out of the show is that because he had insulted the actor who plays George O'Malley for being gay.
