Adults Are Useless: Subverted in Good Burger, played straight in everything else on the show.
Affectionate Parody: "What Do You Do?" Parody of fellow-Nick show Figure It Out, on which most of the All That cast appeared at least once... Bynes, Denberg, & Tamberelli were even regular panelists. The name itself sounds like an older Nickelodeon game show, "What Would You Do?"
Always Someone Better: Baggin' Saggin' Barry experience this when meeting his rival and later-girlfriend Baggin' Saggin' Mary. Old man Clavis even pointed this out while giving Barry some encouragement.
Repairman...man...man... who doesn't really care about property damage and is actively a danger to pretty much everything.
Mark Saul's most common character - an Ax-Crazy kid named Stuart who ties up people and takes over their jobs with insane gusto before leaving atop some imaginary animal once his charade's found out. It started with him as a nutso hall monitor and just grew more psychotic from there.
Miss Piddlin. Her assistant Julio is deathly afraid of her and constantly in a state of panic.
The Backstage Sketch: The show began each episode with the cast getting up to wacky hijinks in the green room before the show. The sketches even had their own Catch Phrase, with the panicked stage manager informing them they have five minutes until the show starts.
Bag of Holding: Baggin' Saggin' Barry had a baggy pair of pants that functioned like this. He had everything in his pants which could possibly fit, and several that couldn't (e.g., an airplane when he kept tripping the airport metal detector until the plane left without him.) In the last sketch featuring him, he found a rival, Baggin' Saggin' Mary, who had the same gimmick, and became his Love Interest. Surprisingly, there was rarely any Rummage Fail situation with either.
Balloon Belly: Twice. First time was during an original era Okra sketch in which a girl demonstrated a "talent" of being able to drink a huge amount of tomato juice, which first shows her becoming visibly bloated, then lead to squicky results of her stomach apparently exploding, which thankfully wasn't shown on screennote okay save for a scene of the audience getting splashed with "tomato juice," a possible case of Getting Crap Past the Radar and Black Comedy. Then once during a Randy Quench skit during the relaunch era, where Randy mistakenly thinks a girl is having trouble breathing and puts an oxygen mask on her, causing her mid section to become humorously gigantic (this too leads to a "boom!", but thankfully in this case we see the girl a few seconds later being perfectly fine aside from her clothes being both tattered and strangely intact all at once).
Good Burger's main character Ed (played by Kel) originally appeared in a sketch called "Dream Remote" where a boy (Josh) uses said remote to order a large amount of pizzas. Ed was the delivery guy and the creators loved Kel's voice for the character so much that Good Burger was created.
Breast Expansion: In one sketch there was a firefighter who forcibly inflated a woman via an oxygen tank and mask. Her breasts started blowing up briefly before she became a huge blimp and then exploding. In another sketch, a superheroine called Megabutt who, as her name suggests, inflated her butt like a balloon.
Clumsy Copyright Censorship: The '90s Are All That airs this show without the musical guest performances. Since this necessitates the additional removal of sketches leading into the performances, and the cast saying goodbye after the song, several episodes end abruptly.
Mother (Lori Beth): THIS IS OUR HOUSE! WE LIVE HERE!
Detective Dan: So if you live here, then why are you robbing your own house?!
Second to Detective Dan is Ed.
Robber: Uh, yeah, I'd like, uh...one Good Burger, uh, Good Cheese, and, uh, all the money in the cash register!
Ed: "One Good Burger with one Good Cheese, and all the money in the cash register!" (Watching all the other customers flee) Hey, where're you going, dude? (Turns back to robber) You're number 73. That'll be eight bucks.
Robber: No! This is a robbery!
Ed: Okay, $2.50.
Companion Cube: The Big Ear of Corn predates the Cube by at least a decade.
Cousin Oliver: Kianna Underwood, Denzel Whitaker, & Lil' JJ, all new cast members for the final season of the show.
Crossover: Sometimes characters from certain sketches make appearances in sketches that otherwise have nothing to do with them (examples include Superdude saving Good Burger from a robber, Jack Campbell showing up on Cooking With Randy and eating all the chocolate and Stuart kidnapping Ask Ashley so he can take over her show).
Taken to it's extreme during the 10th anniversary special in which Coach Kreeton, Abby Rhodes, Principal William Baines Pimpell, Jack Campbell, Detective Dan, Buzz, Caffy, and Randy Quench end up in the same skit. As Principal Pimpell puts it toward the end...
Crouching Moron, Hidden Badass: Ms. Fingerly is a teacher who makes too many bad puns and sings songs clearly meant for preschoolers. She is also capable of matching Ishboo's father at Hookey-Doo (A type of duel from the Foreign Land), out-rocking a popular punk band, and teaching a class with an arrow in her gut.
Descended Creator: In the first six seasons, writer/producer Kevin Kopelow played the show's abused stage manager in the openings. Writer/producer Dan Schneider played the exasperated manager of Good Burger.
Destination Defenestration: A favorite gag across the entire run of the show. Be it hapless people being thrown out of windows, accident prone fools falling out of windows, or most often particularly off-kilter characters throwing themselves out of windows, the writers seemed to think that flying out of a window among the funniest ways you could write a character out of a scene. This occasionally carried over to Kenan & Kel and The Amanda Show as well.
The translations for the various French phrases of Pierre Escargot may come off this way. For example:
May I jump up and down on your sausages? (When Pierre starts saying the English translation, he says, "May I jump up and down on your...", but then stops and says, "I'm not saying it!" before making a silly laugh.)
Duck Season, Rabbit Season: One of the Baby Chat sketches did this so Chester could trick Lulu into expressing disapproval of public funding of private schools.
Edutainment Show: Completely subverted: "Everyday French," "Vital Information," "Don't Do This @ Home/School," "Peter & Flem," "Leroy & Fuzz," and every classroom sketch.
Although "Everyday French" was peppered with real French words that Pierre says before repeating the phrase, this time in English.
And to an extent, "Cooking with Randy & Mandy".
Conversely, every kid knew what "lactose intolerant" meant after every Super Dude sketch... thanks to Amanda Bynes (and before her, Katrina Johnson), and many more kids knew who Ross Perot was after seeing the Earboy sketches.
Flanderization: Detective Dan started off as a by the books police officer who happened to be incredibly stupid. As the show went on, he became a lot more insane, doing things such as going to the bathroom in an air vent and tickling the crooks he was arresting.
Genki Girl: Josh as Tandy Spork. Randy once asked if she was on medication.
Getting Crap Past the Radar: Although most of the translations for Pierre Escargot were pretty innocent sounding, quite a number of them could seem a bit dirtier. Kenan seemed to be aware of it too. In one episode, he struggled to stay in-character as he said "Please stop biting my tennis balls!"
There was one USS Spaceship sketch where after Officer Ulcer failed to get the ship running, he says, "Piece o crap". So, they literally got crap past the radar.
One Baggin', Saggin' Barry skit includes this piece of wisdom.
"You gotta reach down deep in your pants and pull out things you never knew you had."
The background posters during Vital Information were actually quite dirty (I.e. "To Milk cow: Kiss cow, grab udder, yank.")
One early sketch had Alisa having a sneezing fit. Kel asks what's wrong, and it turns out Alisa is allergic to wool. They think it might be Kel's socks, so he takes them off and tosses them off. Alisa's still sneezing though- so they think it might be Kel's shirt. No good- maybe Kel's pants. At this point, Kel's in his boxers and Alisa's still sneezing. Turns out a Little Bo Peep-like lady brought her sheep to the taping.
Amanda asks for a flashlight. Josh Server says "Oh, I have one in my pocket." Later in the same skit, Amanda Bynes stands over Danny Tamborelli in a suggestive manner, before ripping out his still beating heart. She is then nearly groped by one of the other guys, as she tries to pull out Danny's Tonsils.
A customer asks Ed "Change for a dollar?" and he replies "Okay" and starts performing a striptease.
In one sketch, Coach Kreeton calls his son a "misfired chromosome".
Know-Nothing Know-It-All: Miss Fingerly, the school teacher played by Lori Beth Denberg, who rattles off completely incorrect information in all of her lessons and talks as though they're fact. Subverted in that she's mentioned at least once that she knows it's all totally wrong, she just doesn't seem to care.
Muppet: Fuzz, Dead Spice, Oswald, Cheeseburger Doyle
Nepotism: Lampshaded and Double Subverted when Jamie Spears enters the cast: Shane accuses her of having no talent, but she is able to shrink him down to the size of an avocado just by thinking, as well as styling Lisa's hair by breathing on it. When her powers fail to impress the cast, however, she simply bribes them with $5000 each.
Not This One, That One: Two basketball team captains picking their teammates pass over the Butt Monkey for various "players" you'd expect to be much worse, including inanimate objects. The final choice of "you" first appears to be him, but it's the cameraman.
Obfuscating Stupidity: Somewhat implied with Ishboo in the early episodes. Whenever he gets someone to do some of the more ridiculous customs, he will look at the camera and give the audience a "Just as Planned" smile.
Paper-Thin Disguise: One Superdude sketch had a villianess, played by Amanda Bynes, impersonating Superdude(Kenan Thompson). Nobody could tell the difference, except Superdude himself, of course.
Ragdoll Physics: For scenes that involve characters being tossed around or going through a lot of pain, a very obvious ragdoll is used.
Real Men Wear Pink: Superdude who makes it a habit of letting villains and civilians know about his favorite hobbies during his introduction.
Superdude: I also enjoy...three-bean salads and...clipping coupons and...shopping for shoes.
Reunion Show: Two of them, both still during the show's run:
During season 5, the "100th episode" was a live broadcast with Lori Beth Denberg reprising Vital Information one last time, plus interviews with ex-cast Angelique Bates, Alisa Reyes, & Katrina Johnson.
Just before season 10. Server, Thompson, Mitchell, & Tamberelli performed with the current cast. Cannon made a videophone cameo, & several other ex-cast appeared in backstage party segments.
The Okrah sketches usually had three guests per sketch.
The Good Burger sketches had three customers per sketch.
Repair Man (MAN MAN MAN) usually tried to repair three things.
Lori Beth/Danny usually gave three pieces of Vital Information.
Ashley would usually answer three questions.
Pierre Escargot would give three French phrases, which he would then repeat in English.
"Life with Peter and Flem" gave three contrasting examples of what Peter and Flem would do.
In the "Complaint Department" sketches, three customers would complain about what they bought.
"Know Your Stars" gave three "facts" about the star.
"Vocabulary With Lisa and Oswald" from the later seasons had three vocabulary words.
Sadist Show: The appropriately named game show "You Can't Win!" (which actually was the title of a game show parody done on Saturday Night Live during the 1979-1980 season [season five])
Another game show had the loser (Danny) punished in various ways, such as being covered in honey and "tickled" by a bear, or being strapped to a rocket and shot into space.
The Channel 6 1/2 News sketches tended to see Josh Server playing an on-location reporter being consistently abused by whatever surroundings he happened to be in. (For example, nearly freezing to death in the North Pole and being attacked by a polar bear.)
The sketch, "Have a Nice Day With Leroy and Fuzz", which parodies kids shows along the vein of Sesame Street. And which always ends with the sarcastic Leroy (played by Leon Frierson) using some kind of "creative" way of beating up the annoying blue puppet named Fuzz, as a Running Gag.
Scary Librarian: Well, not really scary. Just really loud enough to startle everyone.
Shout-Out: In addition to the countless pop culture references: Amanda Bynes' father is a dentist; at least 2 green room sketches featured Amanda performing oral surgery, plus 1 "Ask Ashley" has her screaming at the audience to brush their teeth, & a one-off sketch features Josh Server as a crazy dentist called "Dr. Bynes."
One sketch featured Ishboo going to the doctor's. When taking a look in his ears, the doctor briefly saw none other than The Ren & Stimpy Show.
A later sketch shows doctor checking Ishboo's nostrils and again seeing the cartoon duo.
One Coach Kreeton sketch was filmed on a set forGullah Gullah Island. Coach Kreeton acknowledges this after several failed attempts to rescue a cat from a tree.
"Crazy Gullah Gullah tree!"
Coach Kreeton is also a fan of Bewitched and he anytime he mentions the show, he will attempt (and fail) to do Samantha's nose twitch.
The intro originally contained a shout out to SNL and the "Not Ready for Prime Time Players" with Soup saying "Not quite live, but ready for prime time."
Special Guest: Only season 7 had them weekly (including return episodes with Bynes & Thompson). In the other 9 seasons, though, Chris Farley, Sinbad, Sherman Hemsley, Dr. Joyce Brothers, & post-Amanda Show Drake Bell all appeared, amongst numerous others. And every single episode had a musical guest.
Spin-Off: Though several shows (listed above) exist because of All That, the only true spinoffs are Kablam! (via Action League NOW!) & The Nick Cannon Show (via the LaTanya character).
The Amanda Show is also a spinoff of All That, due to the combined facts that it was created by Dan Schneider (who produced All That), stared Amanda Bynes, and had frequent crossovers with All That when both shows were on the air.
Police Officer: (after all the customers complain about the crazy things he did) Is all of this true?
Stuart: Of course not. I wouldn't dream of kidnapping the real checkout guy, tying him up, stealing his uniform, and hiding him underneath that counter.
Take That; After a caller continuously tries to get the cast to fall for the "Is your refrigerator running?" prank, Kyle angrily tells him to "try your dumb prank on some Disney Channel show 'cause we're too smart to fall for it!"
The Unreveal: We never find out where Ishboo comes from. Though on a T-shirt his dad (played by Sinbad) brought him, it's actually called Foreign Land and the country resembles Antarctica.
Useless Spleen: Averted in sketch where a character shows and tells about his friend's recently removed spleen. He ends his presentation with something along the lines of "Humans are incapable of surviving without their spleen," at which point his friend gets worried and then collapses.
Weaksauce Weakness: Superdude is lactose-intolerant. Naturally, his foes include Cow-Boy, Butter Boy, Yo-Girl, the Dairy Godfather, & Arch-Enemy Milkman (the former 3 all played by Kel Mitchell & the latter 2 both being Josh Server).
Word Salad Humor: In "Everyday French with Pierre Escargot," most of the "educational" French phrases are word salads, such as "Please remove your banjo from my belly button."
Yank the Dog's Chain: Josh and Kenan tried to help Kevin pull a prank on the girls for once, only for it to backfire when the girls attack him while he was hiding in the giant object he was supposed pop out of.
You Look Familiar: Superdude's equivalent of "It's a bird! It's a plane!" features variations like "It's Ishboo! It's Miss Piddlin! It's Pierre Escargot!" and once, even "It's Kenan!"
Mavis: Hey Clavis! Wake up, the wiki page is over.
