Blushing, LOL. Yes, I know every single song word for word. I know every single line in the entire episode. I know the dance moves. I know everything. I can watch the episode in my head if I want to, I don't even have to turn it on.
I didn't intentionally have this happen either. It's just that I'm over-obsessive, an actress, a singer etc and I have a really good memory. I also know all the dialogue in The Body, The Real Me, Smashed, Welcome to the Hellmouth and many others. Sad, I know but I'm cool like that.
