Quote from Kelly in Trick-or-Treat
Amy: You know, Kelly, you didn't have to change your costume. Kelly: And you didn't have to say I was Jonah's girlfriend, yet here we are. Jonah: Hey, sorry. Just took off my costume real quick. The cowboy hat was itchy. Justine: Oh, my God, you two are Danny and Sandy from Grease! "Summer Lovin'," right? Sandra: Amy, you need to go change into leather Sandy right now.
