These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
But then, anyone looking for "Family Friendly" material from ICP is looking in the wrong place.
Fandom Rivalry: Juggalos vs. Eminem fans, not really because of their music, but their real-life rivalry. Also, Juggalos vs. Maggots, even though Slipknot's own members are Juggalos. ICP and Slipknot are actually mutual admirers, although ICP is not fond of Slipknot's decision to call their fans "maggots".
Fan Hater: Who goes to the Facebook, MySpace or YouTube page of a band you hate every single day just to troll them? Not to mention the Hate Dumb that thinks it's a good idea to publicly call for genocide of that band's fans.
"Miracles" resulted in some people lumping ICP in with creationists, even though the song's about seeing and experiencing things for the first time through the eyes of a child and was written with the rappers' own kids in mind (who appear in the music video wearing their respective daddies' facepaint styles). The lines about how scientists answering those questions are liars probably had something to do with it.
Memetic Mutation: "Miracles", both the music video and some of the lines from the song itself (eg. "Fuckin' magnets, how do they work?", "Magic everywhere in this bitch"). Based on some of their comments, it seems that this might be one of the only recorded successful attempts to create a Memetic Mutation by the creators of the meme themselves.
Paranoia Fuel: "The world famous Boogie Woogie Wu will come to you! Slumber parties, sleepovers, intimate nights, whatever the occasion for the midnight hour, he will gladly come and fuck that shit up!"
Sampled Up: A weird case. "Bowling Balls" samples the Public Enemy interlude "Security of the First World". Most Juggalos recognize the original, but not a reviewer, who believed that ICP sampled Madonna's single "Justify My Love", which samples the Public Enemy beat.
