In addition to his usual gross-out humour, the infamous Comics Nix also makes heavy use of this trope. Typically, he'll use a mish-mash of completely unrelated and often obscure words to describe something or someone, occasionally hiding exactly one relevant term among them.
Comedy music act Worm Quartet's lead singer (and sole member) Shoebox has numerous songs that consist entirely of syntactically correct gibberish. If you listen long enough, things like "my prostitute has evaporated" almost start to make sense.
"Drinking Out Of Cups" by Dan Deacon, a spoken word piece that later became better known when Liam Lynch made a short animation to go with it. Passages like "Who's this guy? Mr. Balloons? Mr. Balloon hands?" and "I'm in love with the seahorses. They're fuckin' unreal. I love them, they're like all the clocks..." were the result of him acting like a macho Long Islander stereotype and spontaneously responding to things he saw while watching a TV on mute (although some people have other ideas about its origins).
Homestar Runner, full stop, with characters often inserting bizarre malapropisms randomly into otherwise normal dialog. There are also the characters Homsar and Senor Cardgage, who only ever speak this way.
Homsar: My name's Millions, and I'm the son of a Chipwich! Senor Cardgage: Carageenan, Montlejohn. Can you detect me to the nearest bus stamp?
LO Lcats seems to revolve around extracting humour from posting pictures of cats alongside AOL-speak.
The earliest "Caturday" pictures had proper language and were still plenty funny, making this another instance of Flanderization.
Taken to its logical conclusion by Eric Idle in the Rutland Weekend Television sketch 'Gibberish', which takes a typical television interview, then simply removes the dialogue and replaces it with random silly words. The sketch with Henry Woolf was then reprised with Dan Aykroyd for American audiences on Saturday Night Live.
"Sick in a cup! Toejam whisper tap Sunderland shower-curtain, ice wallpaper cups grounchingly rubber king wrapped butter kissing-feathers definitely pheasantry daughter successfully douche dinner-bottom."
"Machine wrapped with butter?"
"Machine wrapped with butter."
Space Ghost Coast to Coast and Cartoon Planet just loved this trope, with segments featuring Space Ghost, Zorak, and Brak just saying a single word, such as "pants", back-and-forth to each other for no reason.
Raymond Luxury-Yacht: No, no, no. It's spelled Raymond Luxury-Yach-t, but it's pronounced 'Throat-Warbler Mangrove'.
Interviewer: You're a very silly man, and I'm not going to interview you.
In Gilmore Girls, after Lorelai has just pointed out to Emily and Rory that both "oy" and "poodles" are very funny words
Lorelai: In fact, if you put oy and poodle together in the same sentence, you'd have a great new catch phrase, you know? Like, oy with the poodles already. So from now on, when the perfect circumstances arise, we will use our favorite new catch phrase.
Rory: Oy with the poodles already.
The "Alex Trebek Has Gone Insane" segment of Conan. Through creative editing, Trebek ends up saying things like "J.Lo is slang for someone who communicates by extrasensory means with other Japanese yeast exports."
Calvin: Hey Dad. Know what I figured out? The meaning of words isn't a fixed thing! Any word can mean anything! By giving words new meanings, ordinary English can become an exclusionary code! Two generations can be divided by the same language! To that end, I'll be inventing new definitions for common words, so we'll be unable to communicate. Don't you think that's totally Spam? It's lubricated! Well, I'm phasing.
Father: (Making the peace sign) Marvy. Fab. Far out.
George Carlin (in a list of everyday expressions that make no sense):
"In your own words." You know, you hear that a lot. In a court room or a classroom, they'll say "tell us... in your own words." Do you have your own words? Hey, I'm using the ones everyone else has been using! Next time they tell you to say something in your own words, say "Niq fluk bwarney quando floo!"
The Chef Brian strips from Ctrl+Alt+Del most definitely qualify as this.
Twisp and Catsby from Penny Arcade are basically Chef Brian as two people. (Or possibly Chef Brian is them as one, depending on which came first. This led to accusations of Plagiarism against Tim Buckley, though Chef Brian came first).
Known as Random-Access Humor in Sonichu. It's horrendously unfunny, even when compared to other examples of Word Salad Humor.
Ozy and Millie, occasionally. Usually from Millie. "Armadillo! Armadillo! The cheese from Zimbabwe has lugubriously flattened my popcorn!"
Some of the answers in Tims Chemistry Exam fall into this trope, such as "fork + shoe = spleen".
Bad Lip Reading, a YouTube channel that essentially does elaborate gag dubs of pop music videos (and later, also clips from films and TV shows), uses a lot of this kind of humor. Witness Rebecca Black singing about gang fights and chicken, Ludacris claiming to be "a magic man with a magic goose", and Miley Cyrus wanting to "get dumb and bang a wizard".
@Horse_ebooks, at first glance, is a Twitter bot that tweets random, broken sentences from ebooks (actually part of a Viral Marketing campaign). Initially its tweets were about horses, with the creator running a number of similar bots that focused on other subjects (in a rather pathetic attempt at advertising a shady ebook website), but Horse_ebooks is the only one still standing, as it seems to have a talent for creating entertaining nonsense that inspired people to writefanfiction, draw comics and make posters. It's followed by over a hundred and fifty thousand people.
Rejected's first sketch basically consists of a man saying "Mah spoon is too big" in various inflections, then an anthropomorphic banana appears and yells "I am a banana!", followed by a vacuum cleaner noise. It still manages to be hilarious.
"Tuesday's coming. Did you bring your coat?"
"I'm feeling fat, and sassy."
"I am the Queen of France."
Pinkie Pie, a character in the cartoon series My Little Pony: Friendship is Magic, is well-known for being prone to quirky, nonsensical, random behavior, sometimes resulting in Word Salad-esque lines. The trope appears in an obvious form during "The Last Roundup", in which Pinkie Pie tortures Applejack with inane babbling until she confesses.
"Isn't that just the funnest thing to say? Pickle barrel, pickle barrel, pickle barrel! Say it with me: pickle barrel kumquat, pickle barrel kumquat, chimicherrychunga!"
Spongebob Squarepants has examples like "If I'm lucky, one day Mr. Talent will rub his tentacles on my art!" (The title itself would probably count, if it wasn't a concise description of the protagonist.)
ďYouíve got to be kidding me. Iíve been further even more decided to use even go need to do look more as anyone can. Can you really be far even as decided half as much to use go wish for that? My guess is that when one really been far even as decided once to use even go want, it is then that he has really been far even as decided to use even go want to do look more like. Itís just common sense.Ē
Durwood Fincher, a.k.a. "Mr. Doubletalk", has this as his main shtick. He pretends to be giving people serious interviews, but he mixes in Non Sequitur phrases with complete gibberish. His interviewees are usually too polite to comment on the nonsense, so they try to give legitimate answers to the gobbledygook. Perhaps best illustrated by his Catch Phrase: "What, if any, and if not, how much?"
