* AdaptationDisplacement: Most people tend to think of the TV version first.
* AwesomeMusic:
** When Roy Clark guest-starred, the episode's tag featured him performing his signature piece "Malaguena". The audience, Tony Randall and Jack Klugman were all blown away by the performance.
** Some top-tier American opera singers - [[http://en.wikipedia.org/wiki/Marilyn_Horne Marilyn Horne]], [[http://en.wikipedia.org/wiki/Martina_Arroyo Martina Arroyo]], [[http://en.wikipedia.org/wiki/Richard_Fredricks Richard Fredricks]] - appeared on the show and got a chance to strut their vocal stuff.
* EarWorm:
** Just try to get that Neal Hefti theme out of your head.
** "Happy and peppy and bursting with love!" It takes a little effort to get all the right words in the right places, but the tune is incredibly catchy.
** "A Different Drummer" reintroduced "Stumbling (All Around)", which started its ear wormy existence way back in 1922.
* HilariousInHindsight: The ''movie'' could have starred Tony Randall and Jack Klugman.
* HoYay: And not just to modern eyes: Many a joke has been told about the peculiar nature of Oscar and Felix's relationship over the years. Creator/{{ABC}} was nervous about any such implications, which led Randall and Klugman to playfully film extra scenes with the HoYay dialed UpToEleven, just to give the censors fits.
* InformedWrongness: In "You've Come a Long Way, Baby," Oscar is treated like a complete heel (by Felix, his girlfriend Nancy, and the background music) for wanting to call the police and report a baby that was left behind by his mother at Felix's office several hours before.
* JerkWoobie: Felix. He is the show's ButtMonkey, but others' frustration with him is often justified.
* RecycledScript: ''The New Odd Couple'' reused 8 scripts from the original.
* ValuesDissonance: "The Pig Who Came to Dinner" featured a guest appearance by Bobby Riggs in which he played up his misogynistic public image. If similar statements had been made about blacks, for example, they would ''never'' have been tolerated, but women were apparently AcceptableTargets and Riggs' bigotry was largely played for laughs.
