*Pennywise locks all the school students in a hallway and they all scream and scramble against the wall, Pennywise laughs darkly* Relax! I'm only here for ONE of you! *looks at a piece of paper* now who is...Emily...*looks harder at the paper* oh who cares about the last name *looks up and all the kids scream, he laughs* so now...who is named Emily here?!
