When all the girls are sitting in the (I think it's Rizzo's) bedroom for the sleep-over and they are all talking, you hear another voice. It's pretty loud and I can't tell what it says, but it's not one of the actresses. When my friends and I noticed it, we couldn't believe we didn't hear it at first...it's loud, but not noticeable for some reason, you might have to turn up your TV to hear it, though. Listen closely!!
