While Joi Lansing was indeed the supermodel adored by all male viewers Barbara Nichols was indeed memorable as ditzy blonde Marian Billington whose catch phrase was to affectionately refer to Bob as "Liddy-bear!" ~ The show's instrumental theme song actually had lyrics. Mickey Rooney performed that song "I'm a bachelor guy" on a prime time variety show but sadly I'm unable to find any video or recording of Mickey or anyone singing the song.
