Quote from Joey in The One Where Monica and Richard Are Just Friends
Joey: These little women. Chandler: You're liking it, huh? Joey: Oh, yeah. Amy just burned Jo's manuscript. I don't see how he could forgive her. Ross: Uh, Jo's a girl. It's short for Josephine. Joey: But Jo's got a crush on Laurie. Oh. You mean it's like a girl-girl thing? That is the one thing missing from The Shining. Chandler: No, actually, Laurie's a boy. Joey: No wonder Rachel had to read this so many times.
