* ArchivePanic: While it is impossible to tell how many new viewers have looked at the Vlogbrothers' 1000+ videos (and counting) and fled in fear, the potential is certainly there. Especially taking their [[http://www.youtube.com/user/truthorfail other]] [[http://www.youtube.com/user/hankgames YouTube]] [[http://www.youtube.com/user/theecogeek channels]] as well as non-Website/YouTube [[http://nerdfighters.ning.com/ websites]] into account. The volume really is massive.
* CrowningMusicOfAwesome: Pretty much all of Hank's songs, but some pretty notable ones include "Accio Deathly Hallows", "Book Eight", "People Who Love Giraffes", and "The Anglerfish Song".
* DeathOfTheAuthor: John is a strong proponent of this about his novels. They both feel this way about Nerdfighteria.
* EarWorm: Hank's songs. All of them.
** Also, [[http://www.youtube.com/watch?v=j9CjcQSbVb4&feature=g-all-u the "HITLER and SEX!" theme ]].
* HilariousInHindsight: In 2013, Hank released his annual Franchise/HarryPotter song- this one was called "Oh, JK Rowling", begging said author to please release another book or project. Barely a day later, and it came out that Rowling in fact ''had'', under the PenName Robert Galbraith.
* IncestSubtext: Not usually, but when Hank names his favorite part of John ([[spoiler:his right cheek]]), they mention the fanfiction they may very well have just inspired.
** Jokingly defied when the brothers are doing a joint video, and agree not to end it by saying good-bye, because that would require them turning to each other and staring into each other's eyes.
-->John: Not today, slash fiction writers!
-->Hank: [laughing]: No, not today!
* MemeticMutation: Adding "in my/your pants" to the ends of book titles, an idea originally thought of by Maureen Johnson.
** Puppy-sized elephants.
** And tiny chicken disease (in which tiny chickens lay eggs inside your nose, which hatch baby chickens that eat your brain and poop out of your nostrils. In other words, the common cold.)
** "Dude! No edge!"
** More recently, Hank trying to express frustration over ketchup bottles and self-checkout machines in a discreet manner: "[[{{Angrish}} Passive-agressive...robot...sack of...ketchup...pee!]] '''[[{{Angrish}} Gah!]]'''" It's even been turned into a T-shirt!
** "Remember, this man is an award winning novelist." Used whenever John acts kooky.
* MemeticBadass: The Swindon Town Swoodilypoopers. Specifically, Bald John Green and Other John Green (who is, at it happens, "'''SO STRONG'''").
* NightmareFuel:
** Most nerdfighters would agree that Brotherhood 2.0-era Hank was fairly...[[http://www.youtube.com/watch?v=PNPoDsxAXBw disturbing]]. (And it's [[SincerityMode not]] because he included footage of earwax.)
** If [[{{Squick}} footage of a goat giving birth]] wasn't disquieting enough, wait until you see the techno remix. You get to see it '''[[NauseaFuel reversed]]'''.
** The ending of Hank's video "Do You Believe In God?", where he alters the sound and visuals so that he looks and sounds '''very demonic''' as he jokingly says that he worships Satan. A JumpScare of sorts.
*** Even worse, demonic Hank is in the video's thumbnail.
* {{Squick}}: All the videos about giraffe and giant squid sex.
** Let's not forget the time when [[http://youtu.be/HLkSdHNUpxs?t=27s Hank fell in love with a tree]].
