Invader Zim/Radar

"ZIM after getting hit with a dodgeball: OW! MY SQUEEDLYSPOOTCH! Dib: Did you hear that? He said squeedlyspootch. That's not a human organ! Gaz: I have a squeedlyspootch."
 * One of the most notable and hideous examples is the image of "Bloody Gir," which Nick Toons refused to publish. In response to this, the image has been hidden within a single frame in several episodes. The easiest to spot being the one hidden in the intro of "Mortos Der Soul Stealer"
 * The second most notable is the body count. Hamstergeddon being a good example, with at least one school bus being eaten, and two people being stomped on but totally not killed, or so Nick says. The writers know better.
 * 5 people die in "Attack of the Saucer Morons," according to the Invader Zim wiki.
 * According to the very same wiki, 70 people die in Hamstergeddon.
 * The computer used to evaluate the students' tests in Career Day? The POS 2000.
 * Also in the first episode, the call letters of the radio station that can be seen while Zim does the flyover of the planet? WTFU.
 * In "Battle of the Planets," the seat Dib's sitting on while piloting the butt on Mercury is in the very center of the butt.
 * In "Halloween Spectacular of Spooky Doom," when Dib manages to crawl through the portal in his head, for a brief moment his body is inside out, he hits a fence, and you can clearly see blood on it. And, you know, his organs. Very realistically and Squick-inducing too.
 * Dirty Chicken. That is all.
 * In "A Room with a Moose:" "I'm about to punch you in your wormhole!"
 * Zim threatens to send Dib to a dimension of "PURE DOOKIE"!!! We don't actually see the screen, but it emits a light that turns Dib and the whole room brown.
 * Right at the beginning of "Dark Harvest,"

"Zim: I knew it. EARTH BABIES COME FROM SPACE!"
 * Speaking of "Dark Harvest," that whole episode must have been slipped in under the radar. Way too much Body Horror for Nickelodeon.
 * At one point, Dib is looking at Gretchen with his x-ray goggles and sees that something in her lower abdomen has been replaced with a cat.
 * The episode "Plague of Babies" has Zim walking in on GIR blowing into a power amplifier. Unfortunately, it looks more like he's smoking a bong.
 * Since this episode has a large plot point taking place in a maternity ward, there is always a risk of The Talk coming up. Zim, of course, Lampshades it.


 * From the episode "Walk For Your Lives," Zim says, "Even as a small Irken smeet, my dream was to pass Probing Day like a Sloor beast passes her young. JIGGLY! And full of juice!, and his eye twitches when he says "juice."
 * One alien in Abducted bends over, and its head looks like a pair of naked breasts.
 * In the episode Megadoomer Zim said that Dib has 'stuff' and I immediately got horrible mental images in my head....
 * The frequent references to "dooky" are a literal example of Getting Crap Past the Radar.
