While nearly every last aspect of Down the Rabbit Hole is professionally neutral, there is some light humor thrown in.
In general, he refuses to correct any little mistakes whenever he quotes or transcribes someone. When citing a quote, he will read it verbatim, regardless of spelling or grammar errors. This also means that he will fully transcribe any "uhs" or "ahs" or other unusual Verbal Tics on behalf of the writer, especially when reading things like Diane Kelly's Facebook posts (which may or may not have been written while drunk).
The final words of Furries. Knudsen's completely straightforward delivery just seals it:
"No matter how each person defines it, one thing is for certain; the Furries are here to stay."
In Sonichu And Christian Weston Chandler, when showing a pornographic image drawn by Christine, it is heavily censored by two white boxes, one labeled "nope" and the other "two nopes." Similarly, when talking about Christine's sex doll and video evidence related to it, the screen is shown as all black with the exception of a large "nope," soon replaced by "double nope." In the same episode, Fredrik describes the walls of text in Sonichu as "[taking] up so much space that Alan Moore is put to shame."
GameLife
Guru Larry seemed to pre-emptively know his mere presence was going to be divisive, and so referred to his collaborating with Fredrik like this.
In the Q&A, Geoff Mendicino was asked what he would say to the rest of the GameLife crew if he ever met them again. His answer?
Geoff:(In the tone of a disappointed parent) Why did you do it, Andrew?!
The simple but otherwise very telling "Edited for Brevity" text that slowly fades in when showing footage of DarkSydePhil explaining his financial situation.
There's also the fact that part where he covers DarkSydePhil's prideful fighting game competitor days is named "Chapter 2: Not-So-Humble Beginnings."
The captioner saying they can't stomach DSP's gross eating noises during his food reviews.
During the part where DSP showers with an Axe body scrubber and makes unintelligible noises, the captions outright state that they can't understand what he's saying.
The second half has one absurd moment where Sarah and twelve other soul-bonders conduct a ritual in the living room, while Matt and the other roommates enjoy the show with pizza.
"One roommate demanded that the soul-bonders be ejected, but Matt wanted to gawk at the ritual. So they stood in the kitchen and ate pizza while watching them."
Jen catches wind of the thread chronicling her, and Something Awful behaves as expected:
Hey! Hey! Listen! Hey! I was, err, playing around with this soulbound thing, and I think I screwed up. Hey! Listen! Listen! Hey!
When Diane starts talking shit about an ex-employee being polyamorous straight out of nowhere, even the background music seems to be taken aback.
The fact that Fredrik uses "Meow. Meow. PURR." as The Stinger of the episode.
In The Austrian Wine Poisoning, he reveals that, in the midst of the multinational ban on Austrian wine at the time, China and Japan also ordered a ban on the sale of Australian wine.
The Battle of May Island: After a series of events that can mostly be summed up as absolute shit-show that kept going From Bad to Worse, Fredrik then briefly summarizes the accidents that plagued the M-class submarines based on the K-class hull. The Royal Navy only realized that M2, fitted with a biplane hangar, sank when a merchant pulling into port asked "if it was normal for submarines to dive backwards."
Empress Theresa. He was neutral in his DtRH video on the book and its author, but he proceeds to demonstrate what he's like when he isn't being objective, going over the bizarre insanity of the book that only increases as it goes on. In particular, Fredrik's personal Rage Breaking Point about two-thirds into the stream: While in captivity, Theresa puts together a large bag full of plastic bottles to aid in her escape from a group planning to kill her with an atom bomb. This point is forgotten after several pages worth of meandering prose, until the group keeping her captive puts her on a plane with the bomb, whereupon it turns out that they allowed her to haul the bottle bag with her the whole time - both onto the plane and during the several helicopter flights beforehand. Knudsen is so shocked and infuriated that he immediately gets out of his seat and storms away from the computer for several minutes.
