* GermansLoveDavidHasselhoff: It was a ''huge'' hit in the UK when it debuted on the Creator/{{BBC}} at the start of 1969. Music/TheBeatles loved it; much of the between-song banter on the bootlegged tapes of the ''[[Music/LetItBe Get Back]]'' sessions has them spouting various catchphrases from the show.
* HarsherInHindsight: From their Cocktail Party segment: Judy Carne is kissing Robert Culp but doesn't know who he is. Robert gives her a hint by mentioning his ''Series/ISpy'' costar Creator/BillCosby, but Judy mistakes him for Music/BingCrosby by singing his song "White Christmas". Since then, the joke took on a whole new meaning.
* HeartwarmingInHindsight: A [[NewsParody "News of the Future"]] segment flashes forward to the year 1989 for the rejoicing of UsefulNotes/EastGermany tearing down the UsefulNotes/BerlinWall.
* HilariousInHindsight:
** The "News from the Future" segment from 1968 set 20 years later in 1988 that says President UsefulNotes/RonaldReagan denies that he is a candidate for Governor of California. In 1988, Reagan was ''actually'' finishing up his second term as U.S. president.
** Johnny Brown (an African-American man) portrayed an NBC news anchor for season four's 9th episode about the news, possibly predating Lester Holt's rise to the main anchor spot in NBC Nightly News by 50 years.
** Creator/RichardCrenna at the end of season four playing a commanding officer overseeing Alan Sues' lesser army character in a sketch foreshadows him playing Col. Sam Trautman in the ''Rambo'' films, as well.
** In her guest appearance in season one, Creator/SallyField holds an Oscar and thanks the Academy, about a decade before [[Film/NormaRae she won an actual Oscar for Best Actress]].
** Dick Martin mentions a "Dr. Evil" in the last episode of season four, which [[Film/AustinPowers a certain man of mystery of the '60s]] would know.
** Creator/CharlesFleischer would later be known for playing a very screwy rabbit in ''Film/WhoFramedRogerRabbit'', but in season six's 17th episode he was first seen literally playing different sink pipes and hoses.
* MemeticMolester: Tyrone F. Horneigh, who was always making crude come-ons to Gladys Ormphby and invading her personal space.
* OlderThanTheyThink: ''Film/{{Hellzapoppin}}'' (more the stage version than the film) was a very strong influence on the show despite being three decades older.
* OnceOriginalNowCommon: The show's rapid-fire humor and SmashCut pacing were groundbreaking in its day, but will probably seem downright stodgy to subsequent generations who've grown up with an entire pop culture immersed in that style. (And that's not even counting the dated topical content.)
* SeasonalRot: The series suffered this in the '70s after many of its notable cast members left (Judy Carne, Creator/JoAnneWorley, Creator/GoldieHawn, Creator/ArteJohnson, Creator/HenryGibson, Alan Sues) and its once-cutting edge style quickly became dated. By its final season it was incorporating more traditional variety show elements in-between the rapid fire comedy.
