The label has become well known enough to be parodied. Guns N' Roses 1991 albums "Use Your Illusion 1" and "Use Your Illusion 2" included a similarly-styled sticker saying "This album contains language which some listeners may find objectionable. They can F?!* off and buy something from the New Age section.". Even before official adoption of the label, Frank Zappa printed a satirical advisory message on his album "Frank Zappa Meets the Mothers of Prevention" covers to protest the PMRC's political activities; the message partially read: "This album contains material which a truly free society would neither fear nor suppress."
