Zim was a bizarre, rather twisted cartoon on Nickelodeon that was ultimately canceled because it didn't mesh well with the target audience, which shouldn't come as much of a surprise given that it was created by Jhonen Vasquez, infamous comic artist responsible for

The show basically revolves around the titular alien, who is attempting to subjugate the earth but doesn't do a very good job because he's an idiot. He has a broken robot who attempts to help him, and is thwarted most frequently by a kid so obsessed with aliens and the paranormal that everyone thinks he's insane.
Episode #4 features organ harvesting. Episode #20 features a Ham Demon. The first part of episode #25 is titled simply "Zim Eats Waffles", and in episode #26, Dib's sister has a spell cast on her which makes all food taste disgusting unless made from pork.
