* CloudCuckoolander

* DraggedIntoDrag: A couple of times, Kenan's plans require a girl, which means Kel has to dress up as one. People can't seem to see through the disguise, either (even when he pretended to be pregnant!).
** Only Chris seems to noticed.
* GRatedDrug: Kel's addiction to Orange Soda. There's even an episode dedicated to everyone trying to break his addiction, [[DoesThisRemindYouOfAnything and he suffers from obvious withdrawals.]]

!!Chris Potter

* ButtMonkey: Tons of examples, including the ChristmasSpecial where ''he was beat up by a [[NinjaPirateZombieRobot robotic Santa Claus]] while all the customers sat back and watched'' not even knowing it's a robotic dummy.
* CharacterTics: His eye twitches whenever there's trouble. Though it was only shown in the pilot episode.
* CloudCuckoolander
* MommasBoy
** On the other hand, there's literally no proof his mother actually exists beyond things Chris says. Kenan himself states that he's never met her and Chris's house contains no photos of her, despite them living together. Almost like a lampshade, Chris's fish is called "Norman" ala a certain famous serial killer who also imagined his mother's continued life..
** There was ''one'' episode with some proof: he puts Kenan in charge of the store because he has to take his mother to get her feet scraped. He later shows up with the bag of "foot dust."
* NoodleIncident: He has a boatload of them, all involving his [[HeWhoMustNotBeSeen mother]].
-->'''Kenan:''' Lumberjack school?
* TerrifiedOfGerms: Shown in "The Cold War" when Kel has a cold, though justified as he runs a grocery store and that's where Kel was.
* TokenWhite: Ever notice he's the only white guy in the show?
** The only white ''main character'' at least. There are plenty of white extras and minor characters on the show.
