"No one on Broadway is racist. We all are accepting of all people. Yes, you, from The Color Purple." 
Also, I love the references to "For Good" in Elphaba's dialogue - "I have very limited job options. I mean, just look at me."
"I think that when a movie says it was 'based on a true story,' oh, it happened - just with uglier people." - Peanut Walker, Shucked
