* AlternateAesopInterpretation:
** In this episode, Rarity learns that she shouldn't be ashamed of where she comes from. But what about putting the priorities of your friends first? Isn't that a more fitting moral?
** Twilight threw that moral out the window when she told Rarity to go talk to the Canterlot ponies. Most friends would prefer that their friend do something that will help them get connected rather than a birthday party.
** Besides, acknowledging your roots (hometown and friends, in this case) ''is'' an important lesson, because it makes up a large part of who you are. The only reason Rarity does lie is that she's compromising that.
* AlternativeCharacterInterpretation:
** Did Twilight really not realize that Rarity had twice tried to blow her off for the Canterlot elite (once with the dress, once at the party)? Or did she know all along, and feigned ignorance to help Rarity save face? [[RonTheDeathEater Or was the boorish behaviour of her and the rest revenge?]]
** Were the mane six socially clueless at the Garden Party, or were they serving alcoholic drinks at Twilight's party and had gotten slightly inebriated?[[AbsenteeActor Maybe that's why Spike wasn't present]]…
** Did Fancypants recognize Twilight Sparkle for who she was? He gives a mysterious wink when he refers to her as "this lovely young filly from ''Ponyville''..." If this is true, he may even know a little bit about her personality -- particularly that she dislikes special treatment and that she wouldn't appreciate him announcing her identity.
** For that matter, is Fancypants helping further Rarity's social career from sheer good nature and altruism, or is he just enjoying the way she gets under the skin of obnoxious social-climbers like Jet Set and Upper Crust?
* CrazyAwesome: If the "Party Cannon" doesn't make Pinkie Pie this, then nothing ever will.
* EarWorm: You know the girls' show genre is turned on its head when a song [[note]]Officially [[http://www.facebook.com/dannyimusic/posts/270757059638540 named by Daniel Ingram as "Becoming Popular (The Pony Everypony Should Know)"[[/note]] that sounds ''exactly like a Barbie commercial'' is genuinely good.
* EnsembleDarkhorse: This episode introduced several new minor and background ponies. Fancypants has become quite popular in the fandom, and his unnamed female companion spawned a bunch of fanart within a day of the episode airing.
** There's a funny case with Wonderbolt Fleetfoot. A few days before this episode aired, someone created an OCStandIn out of an OffModel Wonderbolt that appears briefly in "The Best Night Ever", giving her the name [[http://ask-echo-wonderbolt.tumblr.com/ Echo]]. The premise of a blind Wonderbolt was popular enough to get fanart within days... and in this episode "Echo" returns, gets the name Fleetfoot, and wins the race. Said blog adopted it as Echo's surname, and now she's one of the most popular Wonderbolts.
* WhatAnIdiot: Rarity lies to the Canterlot elite about Rainbow Dash, telling them that she's the Wonderbolts' trainer. Does Rainbow not have ''real'' impressive accomplishments, Rarity? Such as saving Equestria ''twice'' and being the only pony ever to perform a Sonic Rainboom?
* SoBadItsGood: Twilight Sparkle's dance is bad enough to drive the elite away, yet it makes Twilight look {{adorkable}}. Much like its inspiration, [[Creator/JuliaLouisDreyfus Julia-Louis Dreyfus]] doing "The Elaine" in ''Series/{{Seinfeld}}''.
* SpoiledByTheFormat: "Hearth's Warming Eve" originally aired before "Family Appreciation Day" and "Baby Cakes", so its plot synopsis was known prior to this episode's airing. As a result, the synopsis that mentioned the *six* friends going to Canterlot to do a play suggested that Rarity would choose her friends over her important business connections.
** [[ForegoneConclusion Not that anyone expected her to keep the business connections]], given [[StatusQuoIsGod the genre of the show in question.]]
* StrawmanHasAPoint: The Canterlot Elite are depicted as smug elitists for treating the ponies from Ponyville as boorish hicks. In addition to Fluttershy ruining the highest profile national annual party, the Grand Galloping Gala (with her friends assaulting several of the party guests to boot), Rarity's friends crash and trash the Canterlot Garden Party (the second highest profile national annual party), making one wonder if the reputation for being boorish hicks is at least somewhat deserved.
* SuspiciouslySimilarSong
** A modified take on Ravel's "Boléro" is used during the scene where Rarity dunks Opal in water.
** In addition, the music played during Twilight's party is a sound-alike of the 1981 Stray Cats song "Rock this Town."
** When HilarityEnsues, the backing music borrows thematically from Khachaturian's "Sabre Dance".
* TheWoobie: It's hard not to feel sorry for the bellhop pony for breaking his back just to do his job.
