The Incredible Jewel Robbery

"The Incredible Jewel Robbery" was an episode of General Electric Theater, broadcast by CBS on March 8, 1959.

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).

Harpo and Chico play Harry and Nick, two inept would-be robbers who try to pull a jewelry heist.

When they are caught and placed in a police lineup, the real Groucho shows up and is immediately fingered as the thief.

Groucho then delivers the only line in the otherwise silent program: "We won't talk until we see our lawyer!"
