- The Season 1 episode "Tangled Web" features several brazenly sexist remarks against Kimiko (mostly from Omi) stating how women are both physically and mentally weak and require men to help them do everything except for cooking. Had the episode not involved Kimiko defying the "damsel in distress" stereotype, the episode might have been banned at worst or toned down due to Executive Meddling at best.
- From the episode "Bird of Paradise":
Jack Spicer: If anybody deserves the Bird, it's me!
Omi: Now, if you all will kindly look away, I feel the urge to scratch in a place that I have never scratched before![Various monkey noises and oohing and oh yeahing accompanied by shots of the others face-faulting, including Wide Eyes and Shrunken Irises, Head-Tiltingly Kinky, and Clay covering Kimiko's eyes with his hat.]
- Likewise, from "Year of the Green Monkey":
- And before that, Jack, under the influence of the Monkey Staff, quite clearly bites Omi's butt. Omi returns the favor, while completely human.
- From the episode "The New Order", after a battle with Chase's jungle cats that are now under Jack's control:
Clay: Well it's not too bad, most of the Wu are still here.Raimundo: Not too bad? It was a disaster! I got cats that bitten in places that I don't even like to think about!!
- A rather stealthy one, in "The Emperor Scorpion Strikes Back", one of Jack's Ring Of Nine Dragons clones is a donkey. A jackass.
- Omi's Blunt Metaphors Trauma can do this sometimes.
Omi: I am in heat!Raimundo: No, Omi, you're "on fire"!
- In "The Demon Seed," Master Fung, Dojo, Kimiko, and Clay get turned into plants. While Raimundo and Omi are tending to them, Omi grabs some kind of apple from Clay's belt area and eats it, causing the horrified cowboy to protest, "Be careful what you go pluckin' there, partner!"
- In "Treasure of the Blind Swordsman", the Blind Seer guarding it has a tendency to mishear things.
Blind Seer: (captured) Hold on! Where are you taking me? I have to use the bathroom!Wuya: (To Jack) What about the treasure chest?
- This gag from "Oil in the Family".
- "In The Flesh" has a really subtle one in which Omi, sitting behind Kimiko, has a wide grin on his face while they're riding on Dojo. If you pay close attention, you'll notice that he seems to be getting a nice view up her skirt.
- How does human!Wuya wake Jack up while he's suntanning in his boxers? She pours a cup of water right on his crotch. Jack's girly screams do not help in any way.
- Dudebot in "The Deep Freeze" basically commits suicide.
- In the same episode Omi holds up a carrot asking if anyone wants to make a snowman - which makes sense in context, but due to how Omi is holding it, the grin and his small figure which makes the carrot look huge in comparison the image itself is rather questionable.
- This exchange in The New Order:
Jack: Well, I've got something that you don't!Chase: *smirking* Very small hands?Jack: *annoyed* No.
- Kimiko's "Fire!" Invocation can look a little questionable if you don't notice that she's wearing tights under her somewhat- Qipao-styled Xiaolin robe. Given that they are slightly lighter than she is, you might miss them.
- In "Something Jermaine" when Omi screws up Jermaine's retrieval of the Shen Gong Wu, Jermaine asks Omi if he's tripping. Either the writers weren't aware that "tripping" is slang for being under the influence of the questionable drug LSD, or the censors didn't. However, it can be neither, as "tripping" (often spelled and pronounced as "trippin'") has been (and still is) used as street slang meaning "to be crazy" or "to be kidding around."
- The "Woozy Shooter" is a Shen-Gon-Wu that emits a gas that causes people to act silly and experience bizarre hallucinations - somewhat similar to the effects of psychedelic drugs (however, the episode arguably portrays the drug experience negatively, as it used against the Xiaolin monks to hinder them during the episode - so this is likely why it wasn't regarded as promoting recreational drug use).
- In "Wu Got The Power" after Jack says something stupid, Hannibal Roy Bean speculates he must have an extra chromosome, a subtle way of implying Down's Syndrome or mental retardation in general.
