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.
Big Lipped Alligator Moment: At one point, the Joker and some other people are in a car. In between some deadly serious seconds of footage, there's a brief scene in which Mister J insists on singing "Juh-juh-juh-Joker face, Juh-juh-Joker face." And that's the last the viewer will ever hear of such songs.
Continuity Porn: The news ticker for Episode 18 is an uninterrupted, unapologetic string of Mythology Gags, so much so that it can distract you from the main video.
Crazy Awesome: The man himself, as well as the series overall.
17. "You know what they say about payback, right? It's a bitch puddin."
The story Joker tells Pearl about how he got his scars. The awesome part is how it seemed so natural that it could have very well been inserted into The Dark Knight itself.
The end of the Joker's hypnotherapy session with Dr. Hugo Strange.
"If this works, and I wake up, and my pants are off..."
"This is Steve. Say hi, Steve."
"...He's shy."
"And here's a lovely picture of your wife...I'm in the wrong office."
"Wake up! Go to sleep!"
The end of #15; Arkham sputtering that there was a shotgun in the trunk the whole time they've been riding around. Including when he was in there.
After escaping the Joker in Episode 16, Dr. Arkham wildly runs to a cop car he encounters while running through the streets. His exasperated reaction when he sees who's driving the car is just priceless.
Episode 17: Jack Ryder's "interview" with Father McHale. "Are you lookin' at her chest?"
Also in 17; "Is that video still up? Damn you, 4479!"
Several in Episode 15, as well as everything Theodore the Bum says.
Crowning Music of Awesome: Well, more like Crowning Moment of Terrifying - The Hall Of The Mountain King in Episode 12, for some reason, is far more terrifying than the Hans Zimmer Joker theme used incidentally throughout.
Fangirls: If you read the comments on the videos, be prepared to either laugh hysterically or weep in fear for humanity. Or both. Especially on Episode 5.
Fanon: With the likely absence of any Nolan-affiliated reprisal of the role any time soon, many fans have come to the see the videos as utterly plausible continuations to the story of the movie...to the point of the still-unidentified "Mr. J" actor garnering dead-serious commentary that he should be chosen as the actual movie successor to Ledger himself.

Fetish Fuel: The Joker eating an apple in episode 6. Just look at the comments!
The Joker mentions that he once bit off a guard's finger in order to get the necessary red for his lipstick. Since then, he hasn't had any problems getting the staff to provide him with the makeup he wants.
The Joker leaving a dead orderly with a bow and a label as a present for Dr. Quinzel.
The Joker has a large white bow on the same shotgun he takes into the wedding - another of his gifts. When he pumps it, the bow falls off.
The Digital Download has some deleted scenes, including Dr. Arkham, having an understandable adverse reaction to the events of the night, getting a really horrible Vomit Indiscretion Shot.
