[[folder: Fridge Brilliance ]]

* Marilyn Monroe got 3 verses, the first and last, while Cleopatra only got two. The third one was clearly a sort of "free throw" for Cleopatra's disgusting "Miss Carriage" joke. Evidently the announcer was ''not'' amused.
* Hulk Hogan's mention of owning Kim Jong-Il in a way akin to a "''WesternAnimation/SouthPark'' puppet show" might seem like [[CriticalResearchFailure an obvious mistake]] [[DumbMuscle on his part]]. However, he's probably thinking of ''Film/TeamAmericaWorldPolice'', which featured the so-called Glorious Leader as the primary antagonist.
* Many of Muhammad Ali's insults towards Michael Jordan are in the same vein of the insults he used in real life to taunt upcoming opponents. He would call them ugly, claim that they were sell-outs to white people ("Uncle Tom" is the term Ali used towards numerous fighters in his career), tell them they look more like a creature than a person, etc. In the battle, he even uses the term "whoop" (as in "I'll whoop you"), and he doesn't use it the way the current generation tends to (usually saying "I'll whoop your ass"), because that's not how he used it in real life.
** Additionally, after his conversion to Islam, calling Muhammad Ali "Cassius" (or "Clay") was [[BerserkButton an easy way to get him pissed off.]] After Jordan actually DOES refer to him as "Cassius," Ali's tone becomes more aggressive and he even threatens to "leave [Jordan] flat on [his] ass."
* Sherlock Holmes' first verse begins with his deduction that Batman is Bruce Wayne. Almost no one in the DC Comics world knows this, yet Holmes was able to figure it out immediately. How was he able to do so? He's a master sleuth who can make connections between entities that almost no one else may have even considered.
* Most rappers have a distinct style that fits the character that the public knows them as (Mr. Rogers talks softly and gently, Mr. T yells a lot, Skrillex uses the "stutter" technique that's popular in dubstep during his vocals, etc.). Two things that stand out to me are Sherlock Holmes and Shakespeare's raps. They both make very good use of multis (multisyllabic rhymes-- i.e., "Deuce stain," "Bruce Wayne." The two phrases rhyme, as opposed to just one word rhyming with another), and they rhyme on the same line impressively ("No gonads, egads, it's so sad"). This could be because Sherlock Holmes is always portrayed as an amazingly quick thinker who can formulate brilliance in almost no time at all, and Shakespeare because, obviously, he's a literary genius. Their rhymes seem to stand out from the other rappers', most of whom use basic rhymes, and sometimes words that don't rhyme at all.
** For the Doctor, I'd probably attribute this to Watsky helping out with his verse. Watsky uses a lot of in-rhyming lines in his songs.
* In the Dr. Seuss vs. William Shakespeare rap battle of WebVideo/EpicRapBattlesOfHistory, I noticed that many other fans claimed that Shakespeare's first verse didn't flow well. But then I remembered the lyric "I hath gone iambic on that ass, ye bastard" and gave it a second listen. Shakespeare's first verse is actually in iambic pentameter and once you realize that, the first verse flows perfectly with the beat. - Kaxbe
** Stephen King vs Edgar Allan Poe has a similar bit: Poe's first line has the same problem of not flowing well to first time listeners. It's in trochee, which is the inverse of iambic.
* During Einstein vs. Hawking, Stephen Hawking sings "I've got 12-inch rims on my chair, that's how I roll y'all". It turns out that really is how Stephen Hawking rolls.
* Hitler says that he prefers the [[Film/{{Spaceballs}} "Rick Moranis version"]] of Darth Vader. Rick Moranis is Jewish. Either he doesn't know about Moranis's ethnicity, or [[UpToEleven he hates Vader more than he hates the Jews.]] Either way, it's hilarious.
** It means he prefers [[Film/{{Spaceballs}} Dark Helmet]] (the character, and Vader's parody) over Vader himself. It may double as an InsultToRocks, since he thinks the wimpy Dark Helmet is a more intimidating opponent than Vader.
** "Little known fact, also dope on the mic" - Not just about the rap battle thing, but referencing how Hitler motivated Germany with his renowned speeches.
* The reason Captain Kirk hates Columbus so much is because Columbus is one of the greatest examples in history of why the PrimeDirective is necessary.
** Also why Kirk's rap derails towards the end into an attack on Queen Isabella.
** Columbus's claims he has 'a neck chop for Spock, I'll put my sword through Sulu' aren't threats, they're boasts - Spock is famous for his 'Vulcan neck pinch' and Sulu is a fencer.
* When Elvis tells Michael Jackson that he has a rap for his monkey, it might refer to Bubbles... or, given Jackson's [[MemeticMolester status among many]], it might refer to [[DoubleEntendre his other monkey]].
* When the Cat in the Hat raps about Theatre/{{Macbeth}}, the blackboard behind him has the equation "1+2=SO MUCH BLOOD". [[{{Foreshadowing}} Later,]] Things 1 and 2 show up and start threatening to stick their feet up Shakespeare's ass.
* The reason why Dr. Seuss never spoke himself and let his creations rap for him? The real Dr. Seuss died from cancer in his jaw/throat area, which made it very difficult to speak in the days before he died.
* It always bugged me how Hitler claimed he went BACK in time to mess with Vader in the prequel. Until I realized, the Star Wars movies were set [[StarWars a long time ago, in a galaxy far far away]].
** Also why Vader claims he's the one who invented everything that Hitler did.
* Hitler tells Vader that he appears to be in pain, right after the latter removes his iconic helmet.
** He also tells Vader to take a trip on his train. The obvious joke is a reference to the transportation of Jews to concentration camps, but it also references one of the several ways his opposition tried to assassinate him; where they bombed the train Hitler was supposed to be on.
* I always thought Hitler could've won the rematch if he'd stopped with his "Sieg fucking heil!" line. Of course, he ''is'' known for going too far...
* Lincoln ''did'' win the Civil War "Four Score and Sixty-Five years in the past". Lincoln Vs Chuck Norris was released in 2010 and was exactly 145 years since the Civil War ended in 1865.
* How come in the Mario Bros. VS Wright Bros. battle, [[ButtMonkey Lu]][[LovableCoward igi]] is the AxCrazy LargeHam? It could be part of his [[SuperPaperMario Mr. L]] personality showing through, partially summoned by his anger towards the Wright Brothers.
** Or it could be because Luigi has [[LuigisMansion previously]] had to fight a dude named Orville.
** It's because the Marios are doing the PublicEnemy bit, with Luigi playing the role of Flava Flav. Notice his bling is about the size of an alarm clock.
** And why are 8-bit fists more badass than quarters? Because quarters are only 2 bits.
* Why does JohnLennon hate Bill O'Reilly so much? Well Lennon was a leftwing activist. If he was alive today, he ''would'' hate O'Reilly and his ilk.
* Hitler refers to Vader as "black". This is not only a reference to his armor's color, but also to the fact that he is voiced by Creator/JamesEarlJones.
* Not necessarily brilliant, but there's something darkly hilarious about a old white guy with a Southern accent telling a black dude to [[spoiler: get the fuck out of his neighborhood.]]
* [[spoiler:The HAL 9000]] going up against Bill Gates makes sense when you remember that [[spoiler:HAL was a [[TakeThat potshot]] at IBM]].
* Beethoven's comment "Ask Bach, I got more cock than Smith & Wesson" seems inexplicable when you know that Bach died twenty years before Beethoven was born. Then you realize Beethoven is probably not talking about THE Bach (that would be Johann Sebastian) but one of J.S.'s equally musical sons, Wilhelm Friedemann and Carl Philipp Emanuel. EpicLloyd (who portrays Bach in the Beethoven vs. Justin Bieber rap) even looks a bit like C.P.E Bach.
* At the end of the Doc Brown vs. Doctor Who rap, the announcer proclaims, "Who won? Who's next?" as he always does. [[spoiler: Then the Doctor comes back to start the rap over and finish it early, thereby winning the battle. Who, indeed.]]
* Shakespeare's SophisticatedAsHell style makes a lot more sense when you realize how many dirty jokes he put in his plays.
* Doc Brown tells the Doctor to not bother trying to out-rhyme him. If you check their lines, you'll see that the majority of the Doctor's lines in either incarnation don't actually rhyme, while Doc Brown had at most one PainfulRhyme (which was the rather excusable Hot-Watts).
* Out of eleven Doctors to choose from, they chose [[spoiler: the Tenth and Fourth]]. These Doctors have been considered to be the most iconic and received great acclaim from fans.
* Barack Obama says that Mitt Romney has a "[[ComicBook/FantasticFour Mister Fantastic]] face." Of course he would - [[OneOfUs Obama grew up reading Marvel comics]].
* Obama vs. Romney is unique in that it was right before an election, and had the power to influence voters. The implications of a one-sided battle would have been enormous, and an indicator of ERB's political leanings. The candidates' bickering and Lincoln's intervention do a crucial job of keeping things balanced.
** It can actually be said that Lincoln could serve as an AuthorAvatar, since his KirkSummation probably told what ERB thought of both Obama and Romney at the time - that [[NiceGuy the former is extremely likeable]], but [[WindbagPolitician just didn't have the guts to really fulfill his promises]], and [[CorruptCorporateExecutive the later was a blatantly pro-business miser]], [[SleazyPolitician who had to resort to dirty tactics and low insults to compete against Obama]] - [[CheatersNeverProsper and was STILL coming out the loser because of it]]. Therefore, ERB can be said to have preferred Obama to Romney - but that was only because Obama was, as Honest Abe, only "[[DamnedByFaintPraise the shiniest of two turds]]", and if ERB had their way, [[TakeAThirdOption neither would be President]] (or at least [[GetAHoldOfYourselfMan Obama would've gotten his act together during his first term]]).
* Why is Clint Eastwood so racist towards Bruce Lee? It's a reference to his character in GranTorino.
** Clint Eastwood was playing dirty. Fitting, as Clint Eastwood (the actor) also played Dirty Harry.
* "You can't have children" is probably the most devastating insult Cleopatra could come up with. Not for emotional reasons, but because Cleopatra, as an ancient queen from a long dynasty, would have heard all her life that having children was the only way to ensure her family's continued rule. And unlike, say, [[HenryVIII Catherine of Aragon]], she ''was'' successful here, having three sons and a daughter. (Granted, one of her sons was murdered and the other two disappeared from the historical record, and this after she died and her kingdom was absorbed by Rome.)
** Likewise, this fact meant her remarks just slammed Marilyn Monroe's BerserkButton even harder - not only is [[DudeNotFunny Cleopatra crossing a line even she'd consider taboo]], but her LackOfEmpathy of the situation - i.e., [[ManipulativeBastard seeing children as tools to]] [[ItsAllAboutMe carry on one's personal legacy]] - probably indicates that Cleopatra would've been an EvilMatriarch, and would've given ParentalNeglect at best, and [[AbusiveParents would've been a nightmare at worst]]. Even though Marilyn didn't get any children, her TheReasonYouSuckSpeech to Cleopatra's TakeThat shows she would've been one HELL of a MamaBear if she did have them.
* In Michael Jackson VS Elvis Presley, during Jackson's second verse, Elvis begins eating sandwiches. He is first shown just casually taking a bite of one like it's a lunch break, but then after Jackson's line "Then you made one daughter, she came to me", he starts wolfing them down faster and looking enraged. He got his BerserkButton pressed by that line and tried to get his anger out by eating while waiting for his second verse, and in that time ended up gaining a lot more weight, hence his transition into "fat Elvis".
* The inclusion of someone named Steve in the Adam vs. Eve fight makes no sense until you remember one of the anti-same-sex marriage arguments was "Adam and Eve, not Adam and Steve".
* In Adam VS Eve, Adam gets the line "When things are good they're great and it's like I'm dreamin', until your junk starts bleeding and you turn to a demon!" This has actually two different meanings; the first is the obvious reference to females becoming crankier when on their period; "turn to a demon" as in turning into a demon. However, in the traditional Adam and Eve tale, Eve was the one who first accepted the forbidden fruit from Satan; hence the second, more subtle "turn to a demon" as in turning and listening to a demon or devil.
* The beat to Gandhi vs Martin Luther King Jr. ended with a gunshot. Both men were shot and killed by assassins.
* Gandhi's comment about staying away from the hoes seems out of place, but Dr. King was known for having a number of emotional trysts. This actually caused him a lot of guilt, which means what looks like an inexplicable opportunity for an awful pun is actually a surgical strike on King's self-confidence.
** It's a double-whammy: He said it applies to protests as well. Hoes in protests? Not so much. But ''hose'' (as in fire hoses being used to disrupt protests)...
* Doc Brown's opening CatchPhrase, "Great Scott!" has double-meaning here -- Creator/DavidTennant, the actor who played the 10th Doctor (the one of the first verse) was Scottish.
* Babe Ruth rips into Lance Armstrong pretty bad for his admission of cheating, but he also makes a reference to calling his shots- there's been a strong debate over whether or not Babe Ruth was cheating by instructing pitchers to throw specific pitches. In "The Babe" he makes several enthusiastic points into the air as if he's eager to hit a home run, while [[http://www.youtube.com/watch?v=15XqYErtEfc actual footage of that very same event from the original game]] shows him merely making a hand gesture to someone- exactly where has been largely debated. Though despite the debate, no actual proof of Ruth cheating ever came to light and the general agreement was that the shot was not called in the manner of cheating, but rather he simply pointed his intent to hit a home run as a taunt to the Cubs and then hit the home run.
** Also, when Ruth hits his home run, the pitcher was Babe Ruth as well. At first, I thought that it was just two of him appearing (happens a lot in rap battles, especially after a character finishes line, and another version appears and starts a new line. Another Santa appearing to say the line, "I'm from the North Pole!" is an example.) But then I realized that Ruth was primarily a pitcher when he played for the Boston Red Sox in the 1910's.
* First, Mozart makes the crack, "I'm a prodigy, sonny, and I'm about to smack a bitch up!". Prodigy's most famous song is "Smack My Bitch Up", and Skrillex's first name is Sonny. Then he says that Skrillex "reeks of dead mouse", a pun on Skrillex's friend/rival Deadmau5.
** Skrillex's line "I'm a rock star, mix you with the bass and drop ya!" seems pretty straightforward; he's making a pun on "drop the bass", saying he'll mix Mozart with said bass so he can drop Mozart while he drops the bass. However, "mixing" in music terminology is when you put a song together and add effects to it so it sounds good. So Skrillex is also making a subtle pun on the term "mixing".
** The Skrillex side of the instrumental has segments that sound like various actual Skrillex songs, whereas the Mozart segments shift over to a more classical music sound.
** Mozart refers to Skrillex's music as "skrill-excrement". Considering Mozart's apparent documented of feces-related humor throughout his life(of which Skrillex insults him for in the prior verse), this crack makes even more sense than being a one-off pun. He does it AGAIN in his next verse when he refers to a part of a Skrillex song as "the 68th measure of diarrhea".
* In his verse, Stalin yells "Shot!" four times. Exactly as many times as Rasputin was shot when assassinated.
* "If your name end with '-in', time to get out." Not just a potshot at the three standing there or foreshadowing [[spoiler:Putin]], but a bonus jab at Boris Yelts''in''.
** "So comrade come at me" = rephrased from the phrase [[Series/JerseyShore "come at me bro"]].
* The real reason Freddie Mercury got on his feet was FrankSinatra implying that ''he was using his bisexuality for publicity'' ("You'll do ''anything'' to get famous!")
** It's also a roundabout [[HypocriticalHumor jab at Sinatra himself,]] who's rumored to have such a background, as well as being resentful of the rise of rock taking away some of his fame. Mercury, in contrast, was out most of his adult life, even when it was more taboo in the 80s, which makes Mercury's [[{{Pun}} rebuttal]] all the [[CrowningMomentOfAwesome stronger.]] It's somewhat implied that Sinatra really ''is'' bisexual (at least in the ERB) review, but made fun of Freddie for being [[ReallyGetsAround too promiscuous]] - as evidenced by the line "[[EveryoneIsBi Look, we all want to swing, baby]], [[EveryoneHasStandards but you took it to far!]]".
* In the season 2 finale, each rapper only gets a single turn. However, if you pay attention NicePeter and EpicLloyd do alternate turns the entire time, keeping with the usual (if modified) formula.
* Why do Santa's elves love bacon so much? It's a great way to keep warm at the North Pole. [[ShapedLikeItself Also, because it's bacon.]]
* The beats in the Season 2 Finale start off grim, then happy, then triumphant. Why? The beats reflect Russia's history. Rasputin's and Stalin's are dark because in their times, Russia wasn't a great place to live in. Rasputin was manipulating the king and millions were starving. Then under Stalin's time, millions of people were dying in camps or getting shot, Poles were being massacred and the Germans were attacking Russia. In Lenin's time, the people were starving and killing off the Tsars and starting a revolution. However, by Gorbachev's turn, where the beat gets very cheerful, Russia was slowly opening its arms to the West and things were improving. When the wall was torn down, Russia was happy for the first time in years. And if you're wondering why Putin's beat is triumphant and uplifting, it's because by the time he was in power, Russia was truly happy and no one was starving anymore.
** Why is Lenin so angry at Rasputin and Stalin? The peasantry of Rasputin's times blamed him for [[TreacherousAdvisor using his position with the Tsarina]], making a corrupt regime worse, and before Lenin's death he had specifically stated he didn't want Stalin to succeed him. After Lenin's death, Stalin went so far as to doctor photos to "prove" Lenin favored him.
* "Who built a superpower, but he paid the price!" Possibly, in addition to its obvious meaning, a subtle call forward to when Rasputin says "If you're the Man of Steel, I spit kryptonite!"; both are Superman references. The first by bringing up superpowers, the second with "Man of Steel".
* Notice how Stalin is having difficulty with ThatRussianSquatDance during the Epic Dance Battle at the end? That's because ''he's not really Russian''. He's actually from Georgia. All the others are from Russia proper:
** Rasputin was born in Siberia.
** Lenin was born up the Volga from Moscow.
** Gorbachev was born in Stavropol, which is south of Moscow.
** Putin was born in St. Petersburg.
* Beethoven's remark about Justin Bieber being a "Little White Usher" actually has a double meaning. The obvious meaning is what is shown in the video, where Bieber turns into a ticket usher; but it also refers to the fact that Music/{{Usher}} is the name of a musician who helped promote him.
* At first, Beethoven's inclusion in the season 2 trailer seems misleading, but then you remember that the Mozart Vs Skrillex battle had a similar premise to the Beethoven Vs Justin Bieber battle: Classical musician Vs modern musician.
* In Master Chief VS Leonidas, how did Master Chief get out of the pit? Simple: he had the Jetpack.
* Also in Master Chief VS Leonidas, Leonidas chides the Chief, saying "I've had better battles with my six-year-old son!" John (the Chief) was taken from his parents when he was six years old, and it was then that he began his forced training and transformation into the Master Chief we know today. Sure, doesn't really work its way into the dis, but it's still a nice little tidbit they slipped in.
* Gandhi's suggestion that MLK plagiarize from him seems a bit odd at first. However, MLK did commit plagiarism in college, which Gandhi was mocking him for.
* Why did Gandhi reject MLK Jr's forgiveness at the end? Because despite Gandhi being a pacifist spreading peace and love, he was borderline racist against black people. See [[http://www.huffingtonpost.com/irene-monroe/the-gandhi-none-of-us-kne_b_842941.html here and ]] [[http://www.dailytimes.com.pk/default.asp?page=story_23-3-2005_pg4_24 here]] [[http://www.gandhism.net/hisownwords.php also here]] [[http://www.theguardian.com/world/2003/oct/17/southafrica.india this one too.]] \\

[[http://www.trinicenter.com/WorldNews/ghandi5.htm This one supported the caste system and detested the "Untouchables."]] \\
\\
[[http://books.google.com/books?id=f6vvy-J7vhcC&pg=PA54&lpg=PA54&dq=gandhi+treatment+of+untouchables&source=bl&ots=ybGwaIHo9e&sig=SfxLfE6FBLJO23dajySN0NIRkrc&hl=en&sa=X&ei=5_VmUuu8HrKy4APr4YHYAw&ved=0CHAQ6AEwCQ#v=onepage&q=gandhi%20treatment%20of%20untouchables&f=false Page 56 of this excerpt on Google Books talks about how poorly Gandhi treated the Untouchables, despite allegedly fighting for their freedom. He basically looked down on them as helpless, stupid subhumans who had to be rescued and couldn't think or act for themselves.]]
* One of Gandhi's lines is "Leave your thoughts on the door, like the real Martin Luther." Martin Luther was also the name of the 16th century founder of the Protestantism (a division of Christianity) who hammered his thoughts on a church door in Germany.
* Boba Fett is only on screen for a short while, barely getting to say anything, but leaving an impact before being unceremoniously killed off. [[ReturnOfTheJedi This sounds about right.]]
* Why does Rasputin keep dancing during Putin's verse? Because Putin mentioned "schooling every communist сука" and Rasputin isn't a communist, so it doesn't offend him.
* Why is Lady Gaga played by [=NicePeter=]? Because, as Sarah Palin alludes to, when she first debuted, many people thought she was actually a transvestite.
* In Vader vs Hitler 2, Darth Vader raps the line "Ask Indiana Jones who the fuck I am". Before this, I always thought because the only reason this line was there because Han Solo and Indiana Jones are both played by Harrison Ford. However, The Indiana Jones movies (or at least the original trilogy) take place in the 1930's, and the Nazis are recurring enemies in the movies. Hell, Indy bumped into Hitler at one point in ''[[Film/IndianaJonesAndTheLastCrusade The Last Crusade]]''. So Hitler had the chance to ask this to Indy in person!
* Hitler makes the IncrediblyLamePun of "A War on Two Fronts" to start off the third rematch. This actually becomes a very clever foreshadowing of the end when you realize that was precisely what led to everything crashing down on him toward the end of World War II.
* Hitler screaming that "You're not going to cheat me!" after shooting Boba Fett is a reference to how Vader was always a CombatPragmatist in the Rap Battles, first by [[TakenForGranite freezing Hitler in carbonite]], then dropping him into the Rancor pit, [[spoiler: before finally [[HalfTheManHeUsedToBe slicing him in half]] with his lightsaber]].
** Also, the fact Vader [[spoiler: [[WhyDontYouJustShootHim only slices Hitler]]]] after Boba Fett was shot also makes sense when, during his lyrics, he establishes the two being TrueCompanions by calling Fett his "homeboy". Vader made [[ButtMonkey Hitler]] TheChewToy ForTheLulz (it would be ForTheEvulz if Hitler wasn't... well, [[AssholeVictim Hitler]]), but [[KickTheDog killing Fett?]] Now ItsPersonal.
* Blackbeard starts by trying to distinguish pirate stereotypes from the reality. Later on, Al Capone makes a bunch of remarks about him having a bunch of crumbs stuck in his beard. This is obviously a case of ShownTheirWork in realizing that the life of an ''actual'' pirate was really quite horrific due to the terrible living conditions of any sailing ship at the time (though pirates would have it especially bad since they'd have to spend the most time at sea). Among other things, most sailors would have very bad hygiene (or in Blackbeard's case, plenty of stuff caught in his extremely thick beard) because they were unable to wash themselves due to a need to conserve their supply of drinkable water.
* Al Capone comments how he's been 'slapping bitch-ass teaches back since I was 14.' Makes more sense when you remember Blackbeard's real name was Edward '''Teach'''.
* When Putin says he's "a President in [his] prime", it works in two ways: when he first became president, he was in his 40s, which is relatively young for a democratically-elected leader to hit the head of state; also, he served as the prime minister of Russia, both before his rise to the presidency, and from 2008 to 2012 (while there are no hard term limits on the presidency in Russia, no president may serve more than two consecutive terms).
* When Pablo Picasso is switching channels on the television, it shows clips of previous battles. In addition to the channel number being the number of that battle, every character who appears on it (Billy Mays, Mr. Rogers, the Fourth Doctor, and Bob Ross) are famous for being on television - Billy Mays for his commercials and everyone else for their own television shows.
* Bob Ross's remark about "dropping bombs like this is Guernica" makes sense when you realize that ''[[http://en.wikipedia.org/wiki/Guernica_(painting) Guernica]]'' was an actual painting by Picasso. Furthermore, the fact that Bob Ross taunts Picasso by making a joke out of it makes sense when you consider the fact that Picasso made it in response to the innocent people killed [[http://en.wikipedia.org/wiki/Bombing_of_Guernica during an actual aerial bombing]] that happened during the Spanish Civil War.
* The line "You fight like the little girls who made your Nike shoes." becomes a much stronger diss after you realize it's coming from a professional boxer.
* Something similar to the Season 2 finale music changes happens in the Donald Trump vs. Ebenezer Scrooge battle. Initially, Trump's beat starts slowly, as Marley took a while to convince Scrooge he was there. After that, Scrooge's beat initially starts out chilly, the high-pitched spikes calling snowfall to mind. The beat gets moving during J.P. Morgan's verse, representing the beginning of Scrooge's road to redemption. Scrooge's second verse retains the chilly atmosphere of his first, but parts of Morgan's theme are still found, meaning that although Scrooge says he wasn't affected, he was shaken slightly. The sudden change starting from Kanye West represents that, in the book, Christmas Present deals Scrooge a few blows that begin to shatter his perception of Christmas as a "humbug". It is kept in Scrooge's third verse, representing the fact that, after the encounter with Christmas Present, Scrooge is truly shaken. Yet to Come changes the beat ever so slightly, as he really drove the point in and made Scrooge understand. Scrooge finally changes his ways in the fourth verse, and the same beat is kept.
* In Donald Trump VS Ebenezer Scrooge, notice how J.P. Morgan appears as ''soon'' as the clock in the background strikes one, and the Ghost of Christmas Yet to Come begins his verse (with "Boo!") as soon as the clock chimes a third time (you have to listen really carefully to notice it chime more than once). However, Kanye appears a second or two ''after'' the clock chimes a second time. In the original ''A Christmas Carol'', the Ghost of Christmas Present (whom Kanye replaces here) appears a little bit after the clock strikes two.
* Why does Scrooge refer to "the Dead Donald's lecture" when Donald Trump is still alive and there was no indication of him dying in the battle? Donald Trump's role in this battle was to inform Scrooge that there are problems with his lifestyle and that he shall be visited by three ghosts who will help him change. In Literature/AChristmasCarol, this role was played by the ghost of Jacob Marley, who had died shortly before the beginning. This is even alluded to when Donald Trump displays a briefcase chained to his arms over his back, similar to how Marley is often depicted being heavily bound in chains with money boxes and various items associated with his life and warns Scrooge that a similar fate awaits him if he doesn't change.
* In Vader vs. Hitler 3, Vader asked Hitler if Napoleon didn't tell him to pack some winter clothes when he invaded Russia. This might seem straight enough, but on a much earlier battle (Napoelon Dynamite vs. Napoleon Bonaparte), Dynamite subtly insults Bonaparte for being one of the things that has failed in Russia, which refers to Bonaparte's failed invasion to Russia. This adds three layers of brilliance:
** Layer one, a Napoleon did indeed say something about Russia, albeit implicitly.
** Layer two, that Napoleon told it to the other Napoleon, so in a sense, Napoleon never told Hitler anything about the whole stuff.
** Layer three, Napoleon Dynamite and Napoleon Bonaparte are played by Peter and Lloyd respectively, who also plays Vader and Hitler. So, in a sense, Napoleon did tell Hitler (or perhaps, Vader himself told Hitler).
* In Bill Gates vs. Steve Jobs, Steve said that 'Windows bit off Apple'. Apple's logo is indeed a bitten apple.
* Genghis Khan vs. the Easter Bunny seems to be a battle of opposites, but they do have one theme in common: Genghis outright stated that he has an enormous amount of descendants in the present day, and [[ExplosiveBreeder what are bunnies known for?]]
* A couple of Youtube comments mentioned that Lloyd doesn't quite have the build to portray Superman. They probably never heard of George Reeves.
** Both Goku and Superman have lines about banging the other's girl - both heroes have notably averted ManOfSteelWomanOfKleenex ''and'' fathered children in at least one version of their stories.
** Superman's comment about how he's going to drop bombs on Japan with his rap seems [[ValuesDissonance off-color]] and [[SuperDickery out of character for him]]... Until you remember that his comics achieved widespread popularity during World War II, at which time he was usually pitted against the Japanese Empire.
** Superman referring to himself as "the OG" makes more sense if you consider that Goku's origin story was deliberately based on Superman's.
** Superman being confident he'll win makes sense if you remember [[WebAnimation/DeathBattle the last time these two clashed.]]
** Goku's line about "One more Superman who's never gonna walk again" is not only a reference to Christopher Reeve who broke his back and became limp, but also a reference to the ''other'' "Man of Steel", [[spoiler:Stalin]].
** Superman's 'tiny genitals' line isn't just a generic diss, it refers to the fact that genitals really did come up in the original DragonBall anime, before they were [[{{Bowdlerise}} rendered nonexistent]] in DragonBallKai!
** When Superman says he'll "freeze (Goku's) whole measly species", it seems like just a stock example of him using his powers... until you realize Gokus entire species WAS snuffed by a villain named... Frieza.
* Of course Batman would call Sherlock a dork. Deerstalker hats (Sherlock's signature hat) aren't supposed to be worn in common, even during Sherlock's time. Those hats are supposed to be worn by hunters or when people go to the countryside, not for everyday city wear.
* In ''Isaac Newton VS Bill Nye'', Nye didn't have many insults so much as backhanded (or even outright) compliments. His persona in ''Bill Nye the Science Guy'' has always been as cheerful and goofy, so in a rap battle, he naturally wouldn't know exactly what to do.
** Also, in Newton's second verse, you can see Nye mouthing along with Newton's lyrics at one point. Nye's job on his show included having to memorize long scientific speeches from scripts; perhaps [[RealityWarper he memorized Newton's lyrics]] [[LeaningOnTheFourthWall from the episode script]] before the fight began?
* When Neil [=deGrasse=] Tyson does his line about Newton's calculation - pointing out that the answer is "i" - his verse acquires a large amount of "i" sounds.
--> '''Tyson''': As in '''I''' put the swag back in sc'''i'''ence wh'''i'''le '''I'''saac Newton was l'''yi'''ng and sticking daggers in L'''ei'''bniz and h'''i'''ding up ins'''i'''de his attic on some Harry Potter business!
** The equation itself is a GeniusBonus if you are aware that the answer to the integral is simply the natural log of the square root of 3, meaning Newton was literally asking Nye for the 64th root of 1. i is a valid answer, but so is 1, or -1, or -i, or any square root of i, or square root of that, or...
* The choice of William Wallace is particularly appropriate - [[http://www.cracked.com/blog/6-forms-modern-depravity-way-older-than-your-grandpa/ the concept of the rap battle originated in Scotland.]]
* George Washington's Continentals are a strong presence in the rap battle, while Wallace's soldiers are hardly seen. Why? The Continental Army post-Valley Forge was very loyal to Washington (in many cases it was the only thing holding the army together) while Wallace was betrayed to the English by a fellow Scottish knight. [[ProperlyParanoid Wallace is right not to trust them.]]
* There's a minor case of UncannyValley with the Turtles' suits in "Renaissance Artists vs TMNT" (the mouths articulate, but not the eyes), but as a dig at the upcoming MichaelBay movie, it makes perfect sense.
* Why does Donatello look like he's dancing up on Da Vinci during his verse? It is believed that he was gay. Da Vinci was generally believed to be gay, as well. "My man Donatello" indeed, but in his case this is less certain. It's equally possible that he was bisexual. Hence why he also gets the line "I love the ladies".
* Each of the four artists is wearing the signature color of their respective turtle. Raphael's red shirt, Michelangelo's orange coat, Leonardo's blue belt and hatband, and Donatello's purple hat and sleeves.
** Not only that, but like the turtles, each artist brandishes a WeaponOfChoice when the announcer says their name: Donatello's hammer and chisel, Michelangelo's mallet, Leonardo's sketchbook, and Raphael's paintbrush and pallet.
* A number of people have pointed out that the Artists get more screen time than the Turtles in their episode. This makes sense - Unlike most ERB characters, the Artists aren't very well-known. Everyone knows Leonardo da Vinci and many know of Michelangelo, but only someone into Renaissance art has likely even heard of Raphael or Donatello. They need the extra time to establish themselves.

* Knowing about the [[https://en.wikipedia.org/wiki/Holodomor Holodomor]] puts Stalin's line about starving Rasputin until he wastes away into an even uglier light.
** "Anyone who sold you pierogi, shot!" Pierogis are a common dish in Poland, and well... [[http://en.wikipedia.org/wiki/Katyn_massacre]]
* Stalin refers to himself as "the man who made Mother Russia his bitch". Fair enough, "Mother Russia" is a common nickname for the country, and he certainly ruled it with an iron fist. But more studious viewers might know that "Mother Russia" can also be used to refer to an AnthropomorphicPersonification of Russia, much like Britannia is for Britain. And considering this ''is'' [[AxCrazy Stalin]] talking, one wonders [[RapeAsDrama what horrors he might be referring to...]]

* In both of his appearances, Abe Lincoln takes pot-shots at the Republican party. Odd, considering that he was a republican and his main opponents (and the people he fought in the Civil War) were primarily Democrats.
** [[FridgeBrilliance Maybe he's upset with how the Republican party has changed since his time?]] The Republican Party of the 1860s and the Republican Party of today are very different from each other, and '''[[RuleOfCautiousEditingJudgment let's just leave it at that.]]'''

* [[spoiler:The 10th Doctor regenerating into the]] '''[[spoiler:4th]]'''.
** RuleOfCool.
** [[WildMassGuessing The rap changed the fabric of space and time enough for that to be possible]].
** He was hit for six. Ten minus six is four. [[ItRunsOnNonsensoleum It's perfectly logical.]]
** The rap was a time loop until he ended. Subsequently it is kinda hard to sort out past from future, so he could have regenerated into a past incarnation instead of a future one easily enough. Also, regeneration is a random process. No rule he can't have the same face twice, or even one we'd never seen before..
** [[TimeyWimeyBall wibbly-wobbly, timey-wimey... stuff.]]
** [[spoiler:It wasn't David Tennant's Tenth Doctor into Tom Baker's Fourth Doctor. It was Nice Peter's ''Twelfth'' Doctor into George Watsky's ''Thirteenth''.]]
** [[spoiler: The Tenth Doctor didn't die - he just pulled a WoundedGazelleGambit (the way [[AlmostDeadGuy he has plenty of time to talk before "dying"]] supports this) before summoning the Fourth Doctor to carry on the battle, while he went behind the scenes [[SetRightWhatOnceWentWrong to reset the Rap Battle before it even starts]].]]
** [[FridgeBrilliance Fridge Brilliance]]: [[spoiler:It is implied in ''Day of the Doctor'' that eventually, the Doctor will regenerate ''back'' into Tom Baker and take on the role of the Curator, as he was revisiting some of his previous incarnations, but "just a few old favorites". With this in mind, it's perfectly possible that he revisited David Tennant's incarnation, and the regeneration seen in ERB is his regeneration into the Curator.]]
** Doc Brown managed to get his hands on a Dalek and made modifications that allowed him to control it via remote, as he does with the Delorean in the first movie. He could have easily modified it with a flux capacitor, giving it a temporal weapon.
* Why did [[spoiler: Vladimir Putin]] appear shirtless?
** It alludes to his MemeticBadass status.
* Why does [[spoiler: Lenin]] claim that Stalin was "supposed to be his right-hand-man" when he specifically did ''not'' want Stalin to succeed him and saw Trotsky as his second?
** It may have been intended as a TakeThat towards Stalin's efforts to rewrite history by claiming he was [[spoiler: Lenin's]] right-hand man. His next line immediately points out that for [[spoiler: Lenin's]] supposed right-hand man Stalin did absolutely nothing to respect his memory. Also, Stalin ''was'' supposed to be [[spoiler: Lenin's]] right-hand man, and served as such for most of Lenin's reign. That doesn't mean he was supposed to be his ''successor'', and it's the shriveling of Stalin's loyalty and the growth of his ambition that led him to start turning General Secretary, the right hand of the Communist Party, into its leader so he could take control.
* How does Wilbur Wright pull his dress shirt off when it's both buttoned and under a pair of suspenders?
** [[ClothingDamage By ripping it.]]
* Why does Joan of Arc claim to be "The Maid of Orleans" when America hadn't even been discovered yet?
** [[http://en.wikipedia.org/wiki/Orleans#High_Middle_Ages Orléans, France]], not New Orleans, Louisiana. Hence why it's called ''New'' Orleans.
* The Rasputin vs. Stalin rap has [[spoiler:all of]] the rappers being very expressive in their speech and movements. [[spoiler:Then you get to Putin, who stands perfectly still save for the occasional ineffective flop of his arm, talking like he just came out of a Rocky movie.]] [[FlatWhat What?]]
** Putin is mainly expressionless most of the time. Think of DullSurprise.
