Which of these TV shows did Kramer appear on in an episode of "Seinfeld"?

Kramer appeared on Murphy Brown in an episode of Seinfeld. The scene occurs in “The Keys,” the 40th episode of the series, when Kramer travels to Los Angeles to pursue acting work.

In the fictional Murphy Brown appearance, Kramer plays Murphy’s new secretary, Steven Snell. The gag builds on Murphy Brown’s recurring joke that Murphy frequently had a different secretary, allowing Seinfeld to turn Kramer’s brief acting job into a memorable crossover-style moment.

Candice Bergen also appears in the Seinfeld episode as Murphy Brown. Jerry and Elaine watch the television scene, while Elaine’s storyline involves writing a Murphy Brown script. The show-within-a-show setup makes the moment easy to misremember as a real crossover between the two sitcoms.

“The Keys” originally aired on May 6, 1992, as the third-season finale. Murphy Brown itself was a CBS sitcom created by Diane English, while Seinfeld aired on NBC, so the appearance was a fictional television clip rather than a conventional network crossover episode.
