"The Incredible Jewel Robbery" was an episode of General Electric Theater, broadcast by CBS on March 8, 1959. It was the first appearance of the three Marx Brothers together in the same scene since A Night in Casablanca in 1946. They had previously appeared in individual scenes in The Story of Mankind in 1957, and in pairs in Love Happy in 1949 (Chico and Harpo appear together; Groucho is in one brief shot with Harpo in the chase scene, and Chico is in a cutaway shot in the wrap-up in Groucho's office). "Jewel Robbery" would be their last joint TV appearance.

CBS explained the show as follows: "If you watch the show you'll see a familiar face equipped with mustache and leer. Because of his contract terms, his name can't be mentioned, but he is not Jerry Colonna." This refers to the fact that Groucho was still hosting You Bet Your Life on NBC.
