Allison Smith and Aileen Quinn have both actually appeared as Annie in some form. While Smith was one of many to play as Annie during the Broadway original, Quinn was only cast as one of the swing orphans. As mimicked by their characters in the episode, Quinn eventually outshone Smith when she was cast as Annie in the 1982 film, Annie (1982).
Karen calls Will a snob. She did the same thing to Grace in the final season of the original run.
