A Virginia couple was arrested yesterday afternoon for having sex in a vestibule of St. Patrick’s Cathedral. Also arrested was a man who was recording them. They might be dismissed as isolated weirdos, but they were participating in a stunt that was being promoted, egged on and profited from by radio talk show hosts known as Opie and Anthony. The pair hold forth on 102.7 FM, WNEW. That is an Infinity Broadcasting radio station, owned by Viacom, a large publicly traded company. Last year, Viacom reportedly signed Opie and Anthony to a $30 million, three year contract. Viacom’s directors include such eminent Americans as the president of the United Negro College Fund, William H. Gray III; the president of Verizon Communications, Ivan Seidenberg; a law professor at Yeshiva University, William Schwartz; and the president of the Bill and Melinda Gates Foundation, Patty Stonesifer. The Opie and Anthony Web site contains such high culture as “The Whipped Cream Bikini Contest,” “The MILF (Moms I’d Like To F) Contest,” the “Whip-Em-Out on Wednesday” contest, and the “Boob-O-Lantern Contest.” We’re not enthusiasts of a blue-nosed approach to broadcasting, but you have to wonder what Viacom is thinking when it promotes a stunt that involves characters copulating in a cathedral.
