Look Hard: Some of the swimmers in "No P in the OOL" return in Operation: C.A.K.E.D. as party guests. Additionally, Kenny and Chimpy from the short "Diseasy Does It" can be seen in "No P in the OOL".
In one scene Lenny's football helmet was only white.
In "No P in the OOL", when Numbuhs 1-5 get launched out of the rocket, Numbuh 4's hair is red inside his pod, instead of blonde.
When Numbuh 4 says "let's do it" in "No P in the OOL", Numbuh 2's voice is heard instead of Numbuh 4's.
(All the partygoers are tied up to their chairs and forced to stay for the party. They sing a for the Delightful Children in a very dull manner.)
All the Partygoers: It's your birthday, not our birthday. It's your birthday, not our birth day. Birthday Hooray.
(A pig-headed Kenny waits impatiently for a cure to "Swine Flu" on the phone)
Kenny: (staring at Chimpy) Hey, Chimpy! Don't just sit there, do something!
(Chimpy starts doing random actions while Kenny is still waiting for an answer on the phone)
Kenny: (notices a box on the wall) "In Case of Swine Flu." Chimpy! The box, Chimpy! Open the box!
(Chimpy opens it, revealing a cook)
Cook: Bam! Look at the bacon sizzle!
(Kenny looks at the bacon, which causes the pig to detach from Kenny's neck and run outside the office window in fear; Kenny eventually regains his original head and stares outside the broken window in awe)
Kenny: Now, Chimpy. If you think that you're gonna--
(pauses, only to find Chimpy climbing on the shelves)
Kenny: Chimpy, get down from there! (Chimpy knocks over some sample jars) Don't do that you're gonna-- (manages to catch one jar) Chimpy! (A giant jar falls on Kenny, then breaks open) Hey, what's that label say? "Swine Flu?" (starts panicking, then rushes to the phone)
Guy on the phone: "Horrible Disease Help Me" hotline. Disease, please.
Kenny: I've got Salmonella Fitzgerald.
(starts singing like Ella and then looks around confused)
Guy on the phone: Salmonella Fitzgerald, like that famous jazz singer Ella Fitzgerald? Wow, you're not gonna believe this. I actually know how to fix this one. O.K., to cure the Salmonella Fitzgerald all you need to do is lick a chimp. Trust me, it works every time. But don't ask where you can get a chimp, especially this late on a Saturday.
Kenny: That's right! It's Saturday! Where am I going to find a chimp to lick on a Saturday? (scats like Ella)
Numbuh 1: Hey, what did you get me?
Numbuh 3: NOTHING! HA HA!
Numbuh 1: Why are we in the kiddy pool?
Numbuh 3: Because the water is nice and warm?
(Everyone in the pool looks down at the water)
Kenny: Now, Chimpy. YOU'RE NOT supposed to be messing around with these jars. There's bad stuff in them. Like this one here called... (Struggling to read) Salmonella.. Fitzgerald. Hmm. Sounds like the name of that famous jazz lady, but it's probably a super-deadly disease! That is why chimps should not be allowed to touch these jars. Chimps are just not careful (turns and accidentally breaks the jar). Excuse me, Chimpy, but I have to go use the phone.
Numbuh 2: This is your captain, Numbuh 2, speaking. At this time we would like to request that you HANG ON TO YOUR UNDERWEAR!!! Wa ha ha ha ha hoo!
Numbuh 1: Numbuh 4?
Numbuh 4: Right. First, I'll be cleanin' your adult-lovin', prissy clocks, and then I'll be takin' that cake.
DCFDTL: Wouldn't you prefer to open the gifts AFTER our little game is finished?
Laura: But I wanna open them (Starts to transform) NOW!!!
DCFDTL: Fine, fine, fine, we'll open the gifts. Just stay calm.
Professor XXXL has a crab arm in "Diseasy Does It".
Diseasy Does It has an alternate title: Chimp-N-Pox.
Operation: C.A.K.E.D. stands for - Capture And Kidnapify Enemy Dessert.
Villain(s): DCFDTL, Laura Limpin, Mr. Wink and Mr. Fibb.
First Appearance(s): Delightful Children From Down The Lane (DCFDTL), Laura Limpin (A.K.A. The Big Badolescent), Mr. Wink, Mr. Fibb.
Operation: C.A.K.E.D. and No "P" in the OOL are both team episodes.
Since this is the pilot short that launched the series, No P in the OOL is the only KND episode that doesn't use an acronym in its title.
Operation: C.A.K.E.D. is featured as one of the Cartoon Network cartoons on the DVD that came with the UK Edition of "Cartoon Network Magazine Issue #78".
"No P in the OOL" was the winner for Cartoon Network's Big Pick Weekend in 2001. Thanks to this episode, Codename: Kids Next Door became the cartoon series it is today.
KND logo: Charlie's Angels
The KND's logo bears a resemblance to the logo of the late 1970s TV show Charlie's Angels in which the main characters' silhouettes are all standing in one place. Also, Numbuhs 3, 4, and 5 are positioned exactly like the silhouettes are in the Charlie's Angels logo.
The Big Badolescent: The Incredible Hulk
Laura Limpin (A.K.A. The Big Badolescent) is an obvious take on The Incredible Hulk, with the difference of getting pimples on her face, instead of turning green like the Hulk.
Episode Title: Chimp N' Pox
This is a pun of the popular, but very annoying disease, "Chickenpox".
Episode Title: Diseasy Does It
This is a pun off of a popular saying, "easy does it".
Mr. Fibb & Mr. Wink: Bond Villains: Mr. Kidd and Mr. Wint
The KND villains Mr. Fibb and Mr. Wink were based from the Bond villains Mr. Kidd and Mr. Wint from the Bond movie "Diamonds Are Forever" (Played by Putter Smith and Bruce Glover). The similarities are uncanny from their looks to their polite, charming and evil style. The only difference is that Mr. Kidd and Mr. Wint aren't mutated from animals.
Ba da ba boom da da da zing da boom da ba!: Ella Fitzgerald
The woman Kenny turned into was the late jazz singer Ella Fitzgerald, as mentioned by the guy on the phone.
