In “Twenty Twelve,” a satirical British television series last year that mocked the shambolic efforts of the fictional Olympic Deliverance Commission to organize the Summer Games, the committee at one point faces a terrible problem: It has somehow failed to find a future use for its 80,000-seat Olympic Stadium. An official known as the “head of sustainability” is reduced to begging an obscure soccer team and the owner of a defunct dog-racing outfit to consider moving in.
