Cloudcuckoolander/Fan Works

Abridged Series
"Marik: By the way, Bakura, your costume could use some work. Bakura: ... what? Marik: I mean, I don't like to criticize, but it looks like your mother made that for you! Bakura: Marik, this isn't a costume. It's my clothes. Marik: Well, you could have done a better job is all I'm saying! Bakura: A better job of WHAT?"
 * Tristan from Yu-Gi-Oh!: The Abridged Series is a combination of a Cloudcuckoolander and a ditz. Almost every line that he gives is an illogical non-sequitur, such as his randomly given cry of "Burn the Witch!" and "Take off your clothes!"
 * The sad thing is, these two examples are him being coherent in the context of the scene. More extreme examples of his CloudCuckoolandiness include "I like pudding!" and "I farted, it's funny!"
 * Marik is this and Poke the Poodle. His evil plans include pushing Yugi off a boat so that his hair will get wet and it'll take hours to dry, and borrowing Yugi's puzzle and not giving it back to him...for at least another 2 months. He also invited Dan Green to the Evil Council because he played a villain in one of the Pokemon movies, and seems to believe that there is a difference between killing someone and just 'destroying them a little'. And then there's the standard weirdness.

"Jamma-P: HEY, I DIDN'T WRITE THIS SCRIPT SO DON'T COMPLAIN TO ME!!!!! Yuri: Wow, someone needs a nap. Momoko: Is it me? Yuri: No. No, it's not Momoko."
 * Momoko from Wedding Peach Abridged:

"Vegeta: Nappa! No! It's a trick! Nappa: But Vegeta! Trix are for kids..."
 * Nappa of Dragonball Z Abridged:


 * There's also Super Kami Guru.

Fan Fiction
"Trying to be normal. He wondered what that was like; to try to be normal. Most people were normal, or normality came naturally. Or behaved however they saw as normal. Even most crazy people thought they were normal. Breech was trying to mirror their behaviour to be normal, and like a mirror, it came off wrong. Identical in every way, but somehow wrong; a facade, an illusion. What must it be like, to have to try to be normal?"
 * The Teenage Mutant Ninja Turtles fanfic The Long Walk has Leonardo musing on the Original Character Breech Loader, thinking about what it must be like to have to try to be normal. Breech Loader is a Cloudcuckoolander with a badly warped appoach to grasping normality, and a tendency to 'lose it' at the most inappropriate of times. As a quote from the story itself:

""I'm going to work on a shrimp farm. Or something. Some kind of farm. Do they farm crabs? I mean, they must. It's not like crabs just walk into the grocery store. Though I guess they could if they wanted to. Wouldn't that be funny? I don't know, maybe not. But I guess if I was farming crabs I might get pinched. What?""
 * Mattie ("The lamp, by the way, is a terrible conversationalist") and Gilbert ("may or may not be wearing only a cape right now") in Part Right, Half Wrong, a Third Crazy.
 * Mattie is a beautiful combination of Cloudcuckoolander and Deadpan Snarker. Where would we be without his arguments with his bedside lamp, among other things?
 * For a moment, Calvin in the fanfic ''Theories About Nuclear Winter when talking to Susie Derkins about working on a shrimp farm in Florida, and wondering if they farm crabs.

"Farfalla's note before one Fan Fic Header: I sometimes refer to slashy bits in canon as 'sardines', because they're thrown like little rewarding treats to us little loyal dolphin-like fans... but that has nothing to do with this story."
 * Kyouko in You Got Haruhi Rolled combines this with The Ditz.
 * flintlockEnthusiast and oceanRising qualify for this, in the Homestuck Fanfic Adult Stuck.
 * TR from BHF5 is the premature lovechild of this and Ralph Wiggum.
 * The main character from Whispers in the Dark, a Percy Jackson and The Olympians fanfiction about the daughter of Thalia and Luke.
 * Author Avatar Art of the Mass Effect self-insert Mass Vexations
 * Major Raikov in the Metal Gear Solid fanfic Stray is "always the type who took sanity more as a suggestion," to the extent that Ocelot considers Raikov's Psycho Electro boyfriend to be the stabilizing influence in the relationship.
 * Demykins from the Kingdom Hearts fanfic Those Lacking Spines behaves in this manner, with a multitude of his lines as shoutouts to other media; when he doesn't quote from various works, he ignores the situation altogether.
 * Which is also the common fanfiction depiction of regular old Demyx, because 90% of the people who write fanfiction have absolutely no concept of what makes Demyx Demyx. Or any other character, themselves.
 * Farfalla The Butterfly Kitten, a prolific Fan-Fic author and creator of the All-Ages Kirk/Spock Archive, is clearly one of these. Just look at her name. Also, only a Cloudcuckoolander could write This. Or This.

Let's Play

 * Raocow takes on a persona like this in his Let's Play entries. See: his Kamek's Revenge Let's Play, where he declares a fear of circles and refers to a flower that spits items when fed an egg or enemy to be "an altar to our dark flesh god".
 * He has weird names for the characters of Super Mario World. He calls Yoshi "stupid horse" even though he is a dinosaur. He calls the Charging Chuck "Football Charlie" because they are in football player uniforms.
 * To quote Raocow himself: "I'M SO GODDAMN WACKY"
 * Marty McSuperfly in Captain Garlic's Let's Play of Icewind Dale 2. Watch out for him when he gets near the wisdom-enhancing items, or goes by the mushroom fields in the Underdark.

Other Fan Works

 * DRACO MALFOY in A Very Potter Musical.
 * Snape is an even bigger example, especially in the Potion Master's Corner.
 * The fan-made role-play Deadly Mistakes has Mathew. Given that he's also a Talkative Loon, he provides a lot of comedy.
