Well, these are very minor but when my sister and I went to see Wicked there were a couple. First, during "Popular" when Glinda said, "Just wear the frock, its pretty!" and threw her wand the wand bounced off of something and kind of flew back at her (Megan Hilty) so she picked it up and threw it again with a little more entusiasm.
Then, during "One Short Day" when they pick up the sunglasses both Megan and Eden picked up the same pair and had a very quick tug-of-war before both letting go and laughing.
Like I said, really small things but still funny!
"I wrote a book: "How to Be Popular". Now I've put together a top ten list of how to help you:
-Elphie, everyday... shower. I mean, who knows? Maybe some of that green is gonna come off!
-Deodorant Elphie. No body likes a stinky witch!
-I think we've covered the hair, we'll get to that.
-Clean underclothes. That's all I'm gonna say.
-Look at your posture. That's no way to be popular!
-Bed made, room straightened. We've done that.
-Colors blended. Oookay.
-But the most important thing to have, to make yourself popular, is to keep your beautiful smile."
