When did elaine date NBC prez

RE: Elaine dating the NBC prez Elaine went out with Russell to save Jerry's show after Castanza put it in jeopardy by gawking at Russell's daughter's breasts. They went out after Elaine flashed her "push-up" cleavage at him over a bottle of Heinz at a restaurant. Jerry's ex (who Kramer "snubbed") was working at said restaurant, and let Jerry know Russ was there in exchange for the "Botticelli's".
