"Every Little Thing she Does is Magic" by the Police. I know everyone and their brother has used this song, but I promised my sister I would make it (and thanks to Nanny McPhee, it's her favorite song). She loves Hermione--I don't. In fact, after making this, I think Emma Watson is a poor actress--and I still think Rupert Grint is underused.
On the bright side: "What comes to mind when I say the word 'Sting'?" -- "That guy that used to sing for the Police? Hey, when he retires, do you think he'll change his name to 'Stung'?" -- "You know, I laughed at first. but would he?"
