Sheila: You were a rotten dancer.
Zach: Why do you think I became your choreographer?
Zach: Goddammit, now can't anybody up there hear me! Just let your hair down! Can't you talk? All of you, just talk, to me, to each other... Jesus Christ.
Bobby: I couldn't catch a ball if it had Elmer's Glue on it. And wouldn't my father have to be this big ex-football hero. Well, he was so humiliated, he didn't know what to tell his friends, so he told them all I had Polio. On Father's Day, I used to limp for him.
Sheila: My mother was kind of middle-aged and frumpy.
Diana: Whose isn't?
Sheila: At fourteen she was middle-aged and frumpy.
Larry: Don't you know the combination, Sheila?
Sheila: I knew it when I was in front.
Larry: You're doing fine, just bring it down a bit.
Richie Walters: A bit? Okay.
Sheila: Why is it only my ass that ever gets invited places?
Answer: The problem is she's "too good" of a dancer. The audition is for a chorus line where the dancers have to perform uniformly and as one unified group. She keeps doing the extra moves and gestures, making herself standout from the others, which is exactly what Zach does not want. He even tells her that she's too good of a dancer to be in a chorus line. She's talented as a lead or solo, but she needs this job. She has to continually restrain herself to blend in.
