These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Archive Panic: 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 otherYouTubechannels as well as non-YouTubewebsites into account. The volume really is massive.
Crowning Music of Awesome: 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".
Death of the Author: John is a strong proponent of this about his novels. They both feel this way about Nerdfighteria.
Hilarious in Hindsight: In 2013, Hank released his annual Harry Potter 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 Pen Name Robert Galbraith.
Incest Subtext: Not usually, but when Hank names his favorite part of John (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!
Memetic Mutation: 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.)
"Remember, this man is an award winning novelist." Used whenever John acts kooky.
Memetic Badass: The Swindon Town Swoodilypoopers. Specifically, Bald John Green and Other John Green (who is, at it happens, "SO STRONG").
Nightmare Fuel: Most nerdfighters tend to agree that "Early Hank" (from the original Brotherhood 2.0 project) was fairly...terrifying. See: this video. (And no, the terror level in that video has nothing to do with the fact that Hank included two seconds of footage of earwax.)
The video where Hank discusses his belief of God has the ending where he pretty much alters the video so he looks and sounds very demonic as he jokingly says he worships Darkness. Definitely a Jump Scare.
Hank's techno remix of footage of a goat giving birth.
Squick: All the videos about giraffe and giant squid sex.
