"There are 10,000,000,000,000,000,000,000,000 particles in the universe that we can observe. Your momma took the ugly ones and put them into one nerd !"
Genghis Khan vs. The Easter Bunny
The announcer's sigh before saying the Easter Bunny's name showing just how ridiculous he thinks the idea is.
Hearing the Easter Bunny call Jesus Christ his "homeboy" is probably humanity's greatest achievement so far.
Take a look at every single Rap Battle previous to this one and you'll notice they all have definite themes (peace vs. war, Evil Versus Evil, conservative vs. liberal, Megapowers vs superpower, and musician vs musician). Then, somehow, for some inexplicable reason, people wanted to see the completely unrelated Genghis Khan and the Easter Bunny throw down, which led to this battle.
Napoleon Bonaparte vs. Napoleon Dynamite
"You're the only type of dynamite that's never going to bang!"
Use some of your force to fix your fucking respirator!
You got one bitch pregnant, then gave into the hate! Now you're 6'6 and black but can't get a date!
Lightsaber? You need a Life Saver!
Master Chief vs. Leonidas
Master Chief refering to Leonidas as 'Fabio Flinstone'.
Leonidas kicks Master Chief down a hole at the end of his first verse. Even the music cuts out and there is a good four seconds of silence while MC just flips head over heels and vanishes. once again it's easy to mistake for the rap finishing suddenly.
Queen Gorgo's mild shrug which seemingly confirms that Master Chief did indeed show her his plasma cannon.
Master Chief: Your whole plan got messed up by a hunchback with Down Syndrome!
Leonidas stating "Ha! I've had better fights with my six year old son!". Right next to him is a small, super imposed Epic Lloyd in a diaper, waving his hands in the air and making angry faces.
Epic Lloyd's ping-pong antics (while dressed in costume, no less!) right at the end of the video. He just says "Point, Sinatra" every time he hits the ball, regardless of whether or not he won. At the last round:
"That your girlfriend back there?" "Yeah." "Next point wins her, GO!" "Wait, what!?" "Point, Sinatra."
And the stinger:
"You're comin' with me baby, let's get some heroin and blow this pop stand."
During Robin's verse, Batman's reactions to his sidekick's rapping in the background. First he just does a kind of "what the hell?" shrug, then looks at his wrist like he's waiting for Robin to finish.
Robin's reaction after Batman throws down a smoke bomb to get away from him.
King: No shoes, no shirt, but I'm still gonna serve ya. / Make you swallow your words so you can break the fast / Then thank God Almighty you can eat at last!
King: Flatten your style like bread. / Naan violence.
Gandhi: You would know about bread, Dr. Birmingham Sandwich. / Boycott those grits / Sit in with some spinach!
The ending involves King enthusiastically hugging Ghandi to forcibly forgive him, but Gandhi is clearly not interested and slides down through King's arms, stopping by his ear long enough to whisper his last lines:
Gandhi: I am passively resisting the fact that you suck. / I am celibate because I don't give a fuuuuuuuuuuck.
Thomas Edison vs. Nikola Tesla
Thomas Edison saying that he's "so dope that I even make New Jersey look good".
Tesla has some:
History is being rewritten, and I have Reddit.
So you can call me Tesla, Nikola, impeccably dressed.
You did not steal from ME, you stole ME from MANKIND!
The Up to ElevenCall Back to Obama vs Romney. First, Lenin interrupts both sides to reprimand them. Doesn't really seem all that fresh, until Gorbachev drops by as well, leading in with a dinky little tune that wouldn't sound out of place in a day care center. Now, the gag gets funny again, but it's when Putin drops by, shirtless, stoic, and generally sounding uninterested does the viewer realize the battle was derailed in the most hilarious way possible.
The cameo appearance of PewDiePie, which Pewdie had foreshadowed in a video and gotten viewers hyped up for? It's him as Mikhail Baryshnikov, dressed in a unitard and dancing. Made even funnier by Mikhail Gorbachev, of all people, saying he "had the balls to let Baryshnikov dance, playa!" While scratching his crotch.
Putin is quite easily the least physically energetic rapper in the series so far (excluding Stephen Hawking and HAL 9000) and it is hilarious when coupled with his deep, loud voice. Not to mention the fact that he sings his lines in this incredible dramatic baritone.
This line is the solid gold breadwinner of the entire season:
Gorbachev: Tore down that wall like the Kool-Aid Man! OH YEAH!
Meanwhile Hitler recoils at first, and then raises his gun with a Slasher Smile. Boba is abruptly blown away mid line, and Vader's sudden surprised act just sells the whole moment. Really, the sheer range of expression they got out of a guy in a non-expressive helmet is a CMOA.
Also, Hitler's Villainous Breakdown after Vader mocked him as a Real LifeGeneral Failure, and on top of that tried to snub his battle by sending in Boba Fett. He simply stops rapping, and instead spews nothing but childish threats:
Tory fails to think of a rhyme and just goes "Uhhhh..."
The faces on the Ghostbusters as Adam tells Tory to say the first thing that pops into his mind— while the Mythbusters, who don't believe in ghosts, don't know where that kind of thing goes, the Ghostbusters are perfectly aware, and are proven right when Stay Puft shows up to the fight.
This bit as Stay Puft shows up:
Stay Puft: Blaze chumps and flip Kari butterside up!
Kari: (sounding offended and pissed off)Hey!
Stay Puft: I smother Ghostbusters in fluffernutter, I don't play; show these dweebs how to rock a beret!
Romeo promises to lie on his stomach so Bonnie and Clyde can lick his ass. Later, we see his corpse with his butt raised in the air, and Juliet screams about Romeo having poison on his face even though she can only see his backside. That's quite some mileage out of one joke about behinds.
The Announcer's absolutely lost reaction at the end of the battle; instead of a boisterous "WHO WON?!" it's this softer and confused "who won...?"
The poison line is priceless in and of itself, especially with how it's suddenly just SCREAMED.
Juliet: Where's Romeo? OH NOMEO! There's poison on your face!
Bonie making light of Mercutio's death at the hands of John Leguizamo.
Romeo: Do you quarrel, sir? Ho, should I draw my longsword, or will you duck your chicken-shit ass back into your Ford?
Juliet: A moment break from your gaze is an eternity past, so together we shall both put these bitches on blast!
How Bonnie perks up after Clyde says they'll rob R&J blind. Outlaw Couple, ladies and gentlemen!
The Meta humour of Grace Helbig and Hannah Hart, who are great friends in real life threatening to kill each other is pretty funny. You can imagine they both had a blast with filming.
Zeus vs Thor
This is a battle between two thunder gods...depicted in the medium of Lego bricks. "Rhymes colder than the frosty balls of your giants" are hilariously wrong when the characters are basically made of children's toys.
When Thor knocks the Jotun off the rainbow bridge it lets out the Wilhelm Scream.
Zeus talks up Greece's historical accomplishments. Thor later retorts:
The little mitten ditty Epic Lloyd does in the BTS video. He's out and about in a snowy forest, complaining about the winter chill and claiming the "frosty LA has his hand tootsies chilly." Each detail begins with a "What?!" and the mitten details pile up...until he finds out that the "snowy forest" isn't real.
