Sort of happened with book two. The artist's mother died, so he rightfully gave her time to mourn. In the meantime, he wrote text only entries.
Series Hiatus: In November 2011, Xin took time off to deal with her dying mother. During this time, the site was updated with the text only "Inner Peace (Through Superior Firepower)", which details Wanda's first few turns of life. The main story resumed June 4th 2012.
Shout-Out: It is easier to list pages that don't have shoutouts to something or other; for instance, Parson once said that when it comes to helping his own cause, Stanley is "somewhere between Gilligan and Starscream."
Some of them are pretty obscure, like the words in Wanda's spellhere◊; one could almost say this thing is inundated with shout outs.
Entire characters show up as one-time references, like "CaptainArcher."
The Lock and Load Montage is full of shoutouts to The Legend of Zelda — a bomb, a Piece of Heart, a Power Bracelet, Hylian Shield, the Master Sword, and what may be the Ice Wand and Boomerang are all scattered around the armory. Also, Shredder's armor can be seen (with Parson taking the right armpiece), and the staff he ends up carrying is Skeletor's. Note that this is the same staff Wanda used towards the end of Book One.
The sword he takes is actually either Aragorn or Gandalf's from LOTR.
A caster from the magic kingdom talking about fate to Parson is a shoutout to George Harrison on the Beatles Sgt. Peppers lonely hearts club band album cover.note His name is even Jojo as a tribute to their song "Get Back" as well, lines from which he speaks in dialogue.
He's also named Jojo Jeftichew, and is a rather hairy Carnymancer
A multi-layered one when Jillian arrives in Aqua Velva and guts one of the governor's pet fish for food. Turns out it was his favorite and named Wanda, the parallels to the actual movie, the titular fish, and the love triangle involving the duplicitous "Wanda" characters are numerous.
It may be unintentional but one could make the argument that it's a shout-out to the The Fairly OddParents. In that show, Wanda is a fairy who often shapeshifts into the form of a goldfish.
In the background of page 66, one of the Thinkamancers with Mister Rogers is Apostle Sanaki.
Zhopa pushes a hobgoblin out of the way and the soundeffect is "Heisman" as in the trophy awarded to the person deemed the most outstanding player in collegiate football. Which makes sense since he was carrying Stanley like a football and used a legal block on the hobgoblin.
Thinkamancer A.V Club is named after a newspaper and bears a striking resemblance to Alyx.
Thinkamancer Pamelor is named after an anti-depressant.
Prince Sammy is from the kingdom of Hagger. Sammy is a rocker. Sammy Hagger is the lead vocalist of HSAS, a hard rock band. The stroke to kill him is represented by the Unsound Effect, "HSAS," solidifying the Shout-Out.
In the 98 strip, the man who yelled, "eat hot cameo" is Chris Miller, aka Firewheels, who was someone who donated a Mac Mini during the Kickstarter which is being used for the motion comic. note See the note section of that page to links with more information.
On page 67,◊ Roger Victor Clarence said the All State slogan, "are you in good hands"?
According to the wiki, Lord Manpower the Temporary is named after Manpower Inc., a company which specializes in temporary work. His death statement, "I can taste key lime pie," is a proper toast when drinking a shot of key lime KeKe, a liqueur. Furthermore, he becomes a "zombie" which is a term that is also used for a type of cocktail which includes fruit flavors, especially lemon and lime flavors.
