Insane Clown Posse is founded upon their own fictional mythology of the Dark Carnival.  It's a concept where souls are sent to a type of purgatory where they await judgment on whether they will be sent to heaven or hell based on their actions. Their style is called "horrorcore" because it incorporates images of over-the-top violence and the supernatural.

So, being accused of plagiarizing "Chicken Soup For The Soul" wouldn't really be in keeping with that image, would it?

Fans of Insane Clown Posse (ICP) are called "Juggalos", and many of them were praising an online video performance by Violent J of ICP in which he read a moving poem and presented it as his own.  But someone called him out on it.  Turns out the poem was allegedly previously printed in an edition of "Chicken Soup For The Soul" and the author of the original poem is suing.

If it turns out to be true, maybe Insane Clown Posse could release an album called "Chicken Soup For The Souls In Limbo" or something just to save face.
