The series revolves around the injokes made with this.
- Halo's Master Chief was correctly identified as a Petty Officernote by his foe Leonidas, which most players are unaware of.
- Freddie Mercury vs. Frank Sinatra referenced Frank's mob ties, the fact that he didn't get in the military during WW2, and the fact that his most famous song "My Way" was actually written by someone else.
- Skrillex claims that Mozart is "into powdered wigs and poop," referencing the composer's infamous penchant for toilet humor. Mozart himself reinforces this repeatedly."In two more months, the world will forget about your Skrillexcrement"
"Tell me, what comes after the 68th measure of diarrhea??" - Most people know very little about Stalin's family, especially the fact that he left one of his sons to die in a German prison instead of trading him for a German Field Marshall. Likewise for his shriveled left handnote , which he was highly self-conscious about throughout his life.
- And as for the Epic Dance Battle in Rasputin v. Stalin, Stalin is having difficulty with That Russian Squat Dance. That's because (as Rasputin points out) he's actually Georgian, not Russian.
- When The Doctor is about to die he cites lines from The End of Time, and the voices echo the Fifth Doctor's regeneration scene.
- They took pains to be as accurate as possible with Stephen Hawking's pose in Einstein vs. Hawking in order to avoid offensive portrayals of the disabled.
- Peter took it upon himself to watch every single episode of Breaking Bad and read up on Dragon Ball after the first half of Season 3 ended in order to prepare lyrics for the episodes featuring characters from the franchises in question - no small feat.
- Superman makes several references to the fact that many Dragon Ball Z characters happen to be named after vegetables, a result of the aforementioned work Peter did.
- A sly one was George Washington bragging about having "the best moves at the ball." He was indeed an excellent dancer
. - Oprah says "Try to beef with me? I'll make the whole market crash!" In the 1990s, Oprah had a guest on her show to talk about mad cow disease and its relationship to questionable practices in the beef ranching industry, at one point declaring she'd never eat another hamburger again. So many people stopped buying beef as a result of the episode that cattle farmers sued Oprah for defamation. She won.
- Lloyd as Hannibal Lecter does the tongue-licking thing just one time, which is notable as many people think it's a recurring Character Tic thanks to Memetic Mutation. For that matter, he also never blinks.
- All of the references to the directors in Spielberg vs Hitchcock, from Spielberg getting mad at Hitchcock, his idol, for not letting him visit (Spielberg grew up watching Hitchcock, was inspired to be a filmmaker from his works, and tried to meet the man, but was refused), to Hitchcock being rejected from fighting in World War I, to Kubrick's desire for utter cinematic perfection resulting in him forcing Jack Nicholson to do a scene 127 times in order to get it absolutely perfect, to Tarantino's Trunk Shot, to how much Michael Bay loves to film shots of helicopters at sunset.
- "Shaka Zulu vs Julius Ceasar" shows us the former's signature "Chest and horns" strategy, facing off against the Roman Wedge, which might break through the enemy lines, leaving the "horns" isolated. It's actually a workable counter...as long as you don't run into the "loins" held in reserve for exactly that sort of tactic.
- Picasso really did have a dachshund named Lump, though he was owned by his close friend David Duncan, who lived with Picasso for many years.
- In Vlad the Impaler vs Count Dracula, Vlad insists that Dracula is a wimp who can "get beat by the sun at the beach" but Dracula corrects him, saying that isn't true. Bram Stoker's novel does indeed show Dracula as being able to stand and move in direct sunlight with no ill effects whatsoever (he just can't use his powers), a fact which has been ignored by almost all of the novel's adaptations.
- "Thanos vs J. Robert Oppenheimer" not only brought up the Thanos Copter, one of the more obscure (and hilarious) pieces of Thanos' lore, but even ANIMATED it.
- Thanos' disses based on Oppenheimer's personal life are indeed accurate- the man slept with two married women and propositioned a third.
- The portrayal of Oppenheimer is based on an interview with the real guy, and captures his worn-out My God, What Have I Done? attitude excellently. Oppenheimer also references accurate nuclear physics in his lines.
- Mansa Musa’s costume was planned to be draped in gold, until a Discord member pointed out that Muslim men don’t wear gold, especially not one as devout as Musa.
- With "Lara Croft vs Indiana Jones", the writers dug deep for material, even hiring on a gamer friend of theirs for revisions, and it paid off, between referencing Jones' deconstruction on The Big Bang Theory to Lara getting the last word about her nude codes.
- "Henry Ford vs Karl Marx" has the team really bring their A-games, going into the writings of both men to get a feel for their personas and how they would rap battle. Two notes in particular are Lloyd discovering Karl Marx's rare skin condition and channeling that element into his performance with a frenetic, aggressive energy, while Peter's research turned up Ford possessing a strange gentle menace, and sought to reflect that in his own performance.
