Insane Clown Posse vs. a Juggalo parody: F**kin' fair use, how does it work?

From The Onion AV Club: "According to members of the Upright Citizens Brigade, the Insane Clown Posse forced the cancellation of a UCB show, after issuing a cease and desist and threatening legal action over Saturday's scheduled "The Gathering Of The Juggalos For A Mother Fucking Baby Funeral" at the group's New York theater."
