Perry and Frank are roommates. Perry greatly envies Frank's expertise with the ladies, which he knows all about because Frank has told him. Well: enter one Deke. Neither Perry nor Frank knows Deke; but he convinces each that he is a good friend of the other and proceeds to move in. Deke is a real ladies' man. He brings his girlfriend in, too; and they move into the bedroom, displacing Frank. When a mysterious man from "the agency" comes looking for Deke, he splits, leaving his girlfriend behind with Frank and Perry. She announces that she has decided to devote herself to sex, and Frank and Perry's eyes get bigger than saucers as they realize now, there's just the three of them! Premiered in London and has had many productions worldwide. An excellent choice for colleges.
