* CargoShip: Kel loves orange soda a lot.
* CrossesTheLineTwice: Kel's response to Brianna saying she wears the sweater her grandma knitted her before she died on special occasions.
-->'''Kel:''' Did you wear it to your grandma's funeral?
* EarWorm: What 90's kid DIDN'T get the opening song stuck in their head from time to time?
* HarsherInHindsight - When Kenan and Kel made a cameo in the RockyAndBullwinkle movie, they made a joke about how their show wasn't gonna be canceled anytime soon after hearing about [[EndOfSeriesAwareness the toons' first show]]. Kenan and Kel was canceled three months before the Rocky and Bullwinkle movie was released. Granted, the timing of that joke could've been on purpose; The final season of the show is very much aware that it's ending, and they were probably starting on it when filming that scene.
** All the friendship moments between the duo can fall into this due to the falling out between the titular actors. Allegedly, Kenan Thompson has distanced himself from Kel Mitchell in recent years to emphasize his career as a adult comedian. However, they [[https://www.youtube.com/watch?v=odQQ4jgGpFU reunited in a Good Burger sketch]] on ''Series/TheTonightShow with Creator/JimmyFallon'', so it seems like they buried the hatchet.
** In the TV Film ''Two Heads are Better Than None'', Roger complains about how a side-of-the-road gas station ends up increasing the price of the gas from a $1.23 to $3.23 a gallon. This becomes ''way'' harder to laugh at considering years after the film, gas prices end up increasing near or ''past'' $3.23.
* HilariousInHindsight:
** In one episode, Kel plugs his headphones into an apple expecting to hear music. About 5 years later, a company called Apple creates the iPod.
** One episode has Roger passing out at his desk, meaning Kenan has to try and help a pilot land a plane. Fast forward to ''Film/SnakesOnAPlane'' and Kenan Thompson is on the other side[[note]]The pilot is killed and he has to try and land the plane[[/note]].
** When interviewing potential actors to play his parents in one episode, one of the couples Kel brings in is Asian. [[spoiler: In another episode, Kenan thinks he might be adopted when he hears of another Kenan Rockmore born on the same day in Chicago. This illusion is shattered when this set of Rockmores turn out to be Asian]].
* IdiotPlot: Everybody in the restaurant in "Freezer Burned" wouldn't have got themselves trapped in the freezer if any of them actually knew where the bathroom was, even with the messed up sign. Also, they would have got out sooner if any one of them actually paid attention to the door if it was going to be opened by someone.
* JerkassWoobie: Kenan's dad, especially in "Get the Kel Outta Here". Kel also qualifies in the same episode as a regular one.
* MemeticMutation
** *sigh* Seriously, TVTropes? Who loves orange soda?
*** Kel loves orange soda!
*** Is it true?
*** ''Mmm-hmmmm'' I do, I do, I doo-oo!
** Don't forget the time he....dropped a screw....in the tuna!
** ''WHYYY!?''
** "Troper, grab a blank... A blank... And a blank... and meet me in a random place!"
* TheScrappy: Due to Flanderization, Kel in later seasons.
** Kyra, as well given how [[FlatCharacter one-dimensional]] and unfunny she was (seriously, all her role consisted of was to be an annoying [[TagalongKid tagalong kid]] with a rather creepy crush on teenaged Kel.) Is it any wonder that [[OutOfFocus her appearances diminished]] throughout the course of the show's run?
* {{Squick}}: Really, just about any thing involving Chris's mother: "Mother loves mashed potatoes, she'll gum these right down!" Or, "I'm so depressed, I'm going to go home and shave mother..." Or the fact that Chris would keep her foot scrapings for really no reason...
* ValuesDissonance: A double example. One episode features Kel dressing up as a woman and marrying Kenan so they can go on a game show. For most of the 2000s gay marriage was such a hot-button issue the sequence wouldn't have happened on a children's show, and in the 2010s it would have created outrage for making the idea of two men marrying into a joke.
* ValuesResonance: Shockingly enough the HotForTeacher episode. Kel is happy to tease Kenan about having a crush on Miss Horn. But when he thinks (mistakenly!) that she's trying to seduce him, his reaction isn't that it's hot or kinky. He pulls off a WhatTheHellHero at the very idea of it, and Miss Horn outright says how inappropriate it would be. Bear in mind this is with a female teacher and a male student.
* WhatAnIdiot: Kel has so many moments of these that it pushes him to Scrappy Territory.
