I saw the first show after the Tony's when Avenue Q beat them to it. So when they're on the bed in the middle of Popular before "Oh Miss Elphaba, you're beautiful", Cheno reflects it in the spotlight all over the audience and goes:
"Oh, it looks just like a Tony!"
My favorite non-ad-lib line was "Well we can't all come and go by BUBBLE!", a old favorite.
Pretty is what changes. What the eye arranges is what is beautiful.
