My guiltiest pleasure is trying to see every Phantom in "The Phantom of the Opera" at least once. My second guiltiest is to see all versions of the story, whether stage or movie. I also love anything that spoofs POTO or Les Miz, including "Forbidden Broadway" and the "It's a Musical" number in "Something Rotten," which has a great line poking fun at Les Miz. (They cut the line from the version sung at the Macy's parade today. .
Audrey, the Phantom Phanatic, who nonetheless would rather be Jean Valjean, who knew how to make lemonade out of lemons.
Another one for Legally Blonde here. I loved it when it was on Broadway and I was just in a production of it about 6 months ago and it was one of the best experiences I've had in over 15 years of being involved in community theater.
