5th Circuit: "You Gotta Suck da Head on dem der Crawfish" not Original In a decision sure to comfort Mystikal fans everywhere, Launch is reporting that the Fifth Circuit has cleared Mystikal of copyright infringement. The court ruled that Mystikal's hit "Shake Ya Ass" did not infringe on Emanation Inc.'s copyright in its handheld toy Cajun in Your Pocket, since the allegedly copyrighted phrases, including the ever-so-erudite "We gon pass a good time, yeah, cher" and "You gotta suck da head on dem der crawfish," were unoriginal, and thus not protected by copyright law.
