* BeamMeUpScotty:
** For some reason, Mister Rogers is famous for saying, "Can you say ____?" The line appears in several parodies but aside from asking his viewers to say "pentagon" in [[EarlyInstallmentWeirdness an early episode]], he literally never said it on the show, and in fact thought the phrase would be an insult to the intelligence of even his very young audience. He ''did'' ask his viewers "Can you _____ now?" at least once, though.
** This trope also applies to the opening theme song. Many people thing the lyrics are "It's a beautiful day in the neighborhood" when it's actually "It's a beautiful day in ''this'' neighborhood".
* CommonKnowledge: Despite rumors, he was never a sniper, nor was he ever in the military, nor did he wear the sweaters to cover up his tattoos. Nobody is quite sure just where the rumors started.
* TheDanza: Quite a few. Bob Trow as Robert Troll and Bob Dog, Joe Negri as Handyman Negri, Don Brockett as Chef Brockett, Audrey Roth as Audrey Paulifficate, Maggie Stewart as Mayor Maggie....
* HeAlsoDid: Creator/MichaelKeaton and [[Film/LivingDeadSeries George A. Romero]] both had behind-the-scenes jobs on the show early in their careers.
* InMemoriam: Episodes 1711 through 1715 ("Mister Rogers Talks about Sharing") are dedicated to longtime musical director Johnny Costa:

* MissingEpisode: "Conflict", aired in 1983, concerned the Land of Make-Believe going into a panic after King Friday becomes convinced that Corny the Beaver is building a nuclear arsenal. At the time, [[SomeAnvilsNeedToBeDropped this was a very relevant plot]], and indeed, was made in response to the ABC television film ''Film/TheDayAfter'', which depicts life before and after nuclear war in a brutal, realistic way; after all, it was UsefulNotes/TheEighties, one of the most tense periods of the UsefulNotes/ColdWar. It was pulled from syndication in 1996, partially due to controversy and partially due to [[TheGreatPoliticsMessUp not being quite]] [[UnintentionalPeriodPiece as current anymore]].
* NeverWorkWithChildrenOrAnimals: [[GenreSavvy Heeded this aphorism]], both to make his show more intimate, and because kids and animals are notoriously unreliable.
* NiceCharacterMeanActor: Completely and utterly averted. Despite whatever fake stories flitter around the internet and other presenters of children's shows, Mr. Rogers took pride in being every bit as warm and friendly in real life as he was on television.
* NoExportForYou: Oddly enough, despite being wildly popular in his native U.S., the show was never broadcast outside of America.
* OneOfUs: Fred said that each of the characters in the neighborhood of make believe had a little aspect of his own personality. We all know if he had Lady Elaine Fairchild in him, he was truly a normal human like the rest of us.
* PromotedFanboy:
** When he mentioned that one of the few TV shows he enjoyed watching was ''Series/DrQuinnMedicineWoman'', the producers arranged for him to be a GuestStar. He played the role of "Reverend Thomas" in his only TV appearance as a fictional human character.
** John Boswell, creator of ''SymphonyOfScience'', is a huge fan of Mr. Rogers, something PBS undoubtedly took into consideration when they commissioned him to compose "Garden Of Your Mind."
* TheResolutionWillNotBeIdentified: The last episode was treated like any other, with the understanding that the show would live on in reruns. Mr. Rogers did show some pictures of his neighbors, and he shook hands with Mr. [=McFeely=].
* TalkingToHimself: Fred Rogers voiced most of the Neighborhood of Make-Believe puppets.
* WhatCouldHaveBeen:
** When ''Sesame Street'''s Big Bird appeared on the show, Rogers' original script called for his performer, Caroll Spinney, to remove his costume and discuss the inner-workings of the Big Bird puppet. Spinney objected, however, because he didn't believe in ruining the [[{{kayfabe}} illusion]] of Big Bird for the children, having been advised not to by Creator/JimHenson. [[CharacterAsHimself Big Bird ended up appearing as himself]] in the Neighborhood of Make-Believe.
** As a compromise, the same episode had Rogers donning a giraffe costume and telling the viewers, "When you see big make-believe creatures in parades or in plays or on television, you can know that the people inside are just pretending to be something else."
* TheWikiRule: Not quite a proper Wiki as such, but the fan-made website [[http://neighborhoodarchive.com/ Neighborhood Archive]] collects an impressive amount of trivia about the show.
