PARIS: I’m sorry, group leader, could you ask the Pigeon sisters if there is a point to this opus?
The Pigeon sisters are characters from the film The Odd Couple, previously mentioned. They are English sisters named Cecily and Gwendolyn Pigeon who live in the same building as Felix and Oscar. They were played by cousins Monica Evans and Carole Shelley in the original Broadway play, the film, and the 1970 sit-com, although their roles were gradually phased out in the television show.
The Pigeon sisters are friendly, flirtatious, ditzy, and as their name suggests, slightly bird-brained, rather like Louise and Madeline. Paris has no problem tearing down her friends in public; no wonder that Rory isn’t sure whether Paris is her friend or not.
An opus is an artistic work, especially one on a grand scale.
