Cambridge appeared on several network television programs, including "Car 54 Where Are You?" ("The Curse of the Snitkins"), "The Dick Van Dyke Show" ("The Man From My Uncle"), "I Spy" ("Court of the Lion"), "The Monkees" ("It's a Nice Place to Visit"), and Police Story ("Year of the Dragon"). He also had a small speaking part as a member of Sgt. Bilko's platoon in "The Phil Silvers Show", 1957 episode "Boys Town". Cambridge gave an acclaimed performance alongside Tom Bosley in the episode "Make Me Laugh" of Rod Serling's "Night Gallery", a story about a failed comedian who looks to a genie for a quick fix to success; the episode was directed by Steven Spielberg. He perhaps reached his largest television audience in a series of comical commercials for Jockey brand underwear.
