After Candice Bergen and the set of Murphy Brown (1988) made a guest appearance in the Seinfeld (1989) episode The Keys (1992) - where Kramer (Michael Richards) is hired as an actor to play Murphy's secretary - Jerry Seinfeld and Larry David returned the favor by appearing as themselves on this other sitcom by Murphy Brown creator Diane English, where they receive a Seinfeld script written by a Blue Shamrock customer, in which Kramer sleeps with Elaine (Julia Louis-Dreyfus). This also echoes Elaine's writing a Murphy Brown script in the above mentioned Seinfeld episode.
