- Just about anything involving Coach Kreeton. Slapstick at it's finest.
"Once upon a time, there was a sad miserable man named Coach Kreeton. That's ME!"
- In one sketch, he has to babysit a young boy. When the boy wants to hear a story, Coach Kreeton reads him one about himself.
Girl: Can I go to the restroom?
- In another one:
Coach Kreeton: NOOOOOO!! YOU'RE GONNA SIT THERE UNTIL YOU EXPLOOODE!!!
- An early Ms. Fingerly sketch where the students are taking a test and one girl keeps cheating in different ways (looking over someone, asking someone, using a telescope because a student was covering her answers, using a ham radio, and finally asking Abraham Lincoln himself). Ms. Fingerly had enough and took her to the principal's office. As soon as they leave, the students start asking each other for answers, asking Lincoln, and using the radio.
- Anything with Superdude, especially when his one weakness, dairy products, came into play.
- All of the absurd pieces of advice from "Vital Information for your Everyday Life" sketches. For example:
Lori Beth Denberg: If you're doing your homework and it's too hard, don't go up to the teacher and say, "This homework is too hard! Now give me a big wet kiss!"
- "This is no way to treat the world." *punches a globe*
- "If you're a girl and your bra is too tight, you're uncomfortable. If you're a boy and your bra is too tight, I'm uncomfortable."
- "It's rude to run around the forest screaming 'ME HATE THE TREES! ME HATE THE TREES!'"
- "It's a good idea to leave milk and cookies for Santa. It's a bad idea to give him liver and elf juice."
- "Miz Piddlin almost let her maniacal rage get the best of her!"
- A highlight of "What Do You Do?", a parody of Figure It Out, comes after Coach Kreeton correctly guesses the first contestant's talent ("Kayley licks lobsters."). Kayley would have won a dollhouse if she stumped the panel, but since she failed, the dollhouse gets crushed by a wrecking ball.
- During this particular sketch, other school characters are on the panel, but so is Kevin. He's not wearing pants, either, much to the annoyance of Coach Kreeton (who's sitting right next to him).
- One "Ask Ashley" sketch gets interrupted by Dr. Joyce Brothers, who gives Ashley some advice on holding her temper. Ashley thanks Dr. Brothers for the advice, and invites her to answer the next letter. She learns that it comes from a boy who doesn't consider turning on his lights when having to walk around during the nighttime, and gets pissed as strongly as Ashley usually does when giving advice to those Too Dumb to Live.
- Ashley's reaction when she gets a letter from a kangaroo...
Ashley: YOU'RE A STINKIN' KANGAROO!!!! (suddenly sounding cute again) A very special kangaroo who can write letters (gets angry again) BUT A KANGAROO NONETHELESS!
- Ashley's reaction when she gets a letter from a kangaroo...
- From the 10th Anniversary Special, one skit in particular started as a mishmash of the old skits with the new, involving Coach Kreeton, Principal Pimpell, Detective Dan, Fat Cop, Buzz and Kaffy, and Randy Quench. It starts out with Kreeton and Pimpell and then just becomes more insane and bizarre as it goes on. Pimpell even lampshades it by stating "this sketch is clearly out of control!" when Randy Quench shows up.
- This entire sketch could be considered commentary on how the comedic styling of the show evolved between the original cast and the new cast since it doesn't become quite so convoluted until Buzz and Kaffy are brought in by Abby, quickly proceeded by Randy Quench who destroys the set with his fire hose.
- One cold opening featured Josh describing how the kids got to become cast members. The flashback of the audition process includes Lori Beth building a card mansion, Kel eating 540 cocktail weenies, Josh competing on Nickelodeon Global Guts, and Katrina pulling an 18 wheel truck!
- One "Cooking with Randy & Mandy" sketch featured Randy getting a cavity. When a dentist showed up and told him he can't eat chocolate for two weeks, Randy immediately fainted. Later, he pulled out his tooth to avoid the wait.
- "Know Your Stars" could be rather funny at times.
- The first Detective Dan sketch featured a wealthy woman, played by Lori Beth, whose jewelry was stolen from her safe. Detective Dan's response to the woman showing him her safe was broken into:
Detective Dan: Lucky for you this safe is empty.
- ALL of the "Everyday French with Pierre Escargot" sketches.
- Ed in one sketch becomes the temporary Good Burger manager and ends up firing one of the customers.
Customer (Played by Amanda): But I don't even work here!Ed: I know. I just fired you. Now I'm gonna have to ask you to leave.Customer: You're crazy! Crazy, you know that!Ed: Well, at least I have a job.
- Tandy Spork.
- During the Good Burger sketch in the anniversary show, Ed shows off the very first Good Burger he ever made. which can only be described as a lump of mold trying to pass itself off as a hamburger. Bernie Kibbit is understandably horrified.
Bernie Kibbit: WHAT IS THAT?!Ed: This is the first Good Burger I ever made. I keep it under my bed!Bernie Kibbit: THAT'S A TRAGEDY ON A BUN!
- Bernie then has a heart attack.
- Later, Kenan enters as Lester Oaks, Construction Worker—only to end up getting sprayed with chili. This part is also notable for the Corpsing, as Kenan and Kel try so hard not to burst out laughing.
- The "Cooking with Randy" segment that featured Chris Farley. Just picture Matt Foley as a chef obsessed with ketchup.
- Anything with RANDY QUENCH, VOLUNTEER FIREMAN! Here comes me! At which point he causes chaos- thanks to him forgetting his meds.
- Fat Cop "investigating" the disappearance of Randy's fork on "Cooking with Randy".
- Detective Dan ruining Helga's wedding.
Helga: YOOOOUU! You have angered Helga! (grabs Dectective Dan by his trench coat) Now, you must pay!Detective Dan: Don't mind if I do!
- The 100th episode features Danny Tamberelli all psyched about the 100th episode until he realize he's late. So he spends most of the episode trying to get to the studio, which includes riding a bike on the freeway. By the time he made it, he's all beaten, his clothes torn and it's already over.
- An opening skit where Kel wakes up from his nap and finds his legs are still asleep. The other cast, unaware of Kel's predicament, tells him to stop messing around and get to the stage. One of his attempts at standing up has him move his legs like a breakdancer.
- The cast is disgusted during one of the opening skits when they learn that one of the sketches is going to involve them ingesting a whole pound of raw liver. In order to get out of it, each of the cast members gives Kevin an excuse note. In true All That fashion, all of the excuses are rather ridiculous, ranging from being excused for having a bad hair day to being forbidden by their mother. The latter is especially hilarious as that excuse came from the director.
Kevin: "Please excuse Josh from the Liver sketch. He's having a bad hair day."Josh: You're lucky you're bald, pal.Kevin: Yeah, well, I had it cut this way!Josh: Sure you did, Kev.Kevin: "Please excuse Alisa from the Liver sketch today. Her left arm fell off. Signed her doctor?" Well, there's your arm! (Points at her clearly attached left arm) Look! Arm!Alisa: Are you a doctor!Kevin: No—Alisa: I don't think so!Kevin: Well, I know what an arm looks like!Kevin: "Malcolm-Jamal Warner cannot direct the Liver sketch!" There's no reason. Why?Malcolm: Because my mom said no.Kevin: Now I feel bad.
