Douglas Darden laughter was the laughter of three young girls, who were, in essence, their clients: the fourteen year-old twins, Cass and Polly, and their nineteen-year-old friend, Helen. Cass and Polly are most likely feminized renderings of the celestial twins of Greek mythology, Castor and Pollux (better known as Gemini), and their sister, Helen of Troy. Many of his original sketches and drawings for Oxygen House are now owned by the Museum of Modern Art, along with a select few of "Sex Shop" drawings; gifts of Darden's widow. The remainder of his drawings are held at the Avery Architectural and Fine Arts
Castor and Pollux carried the women off to Sparta wherein each had a son; Phoebe bore Mnesileos to Pollux and Hilaeira bore Anogon to Castor. This began a family feud among the four sons of the brothers Tyndareus and Aphareus. The cousins carried out a cattle-raid in Arcadia together but fell out over the division of the meat. After stealing the herd, but before dividing it, the cousins butchered, quartered, and roasted a calf. As they prepared to eat, the gigantic Idas suggested that the herd be divided into two parts instead of four, based on which pair of cousins finished their meal
