The Bob Newhart Show Season 4 Episode 9

Bob's asked by Ruth Corley ('Jennifer Warren'), to appear on her morning interview program. After taking up the charming, and demure-sounding Ruth on her offer, she turns into a cut-throat host, on-air, who has Bob in her clutches, and he lets it slip that one of the patients he's treated, is a politician, and everyone begins guessing who that person could be.
