Cards Against Headquarters is Cards Against Humanity, but with PPC-themed decks. Like the original CAH, it is NSFW, NSFB, and should not ever be played by children. You shouldn't play this game, either, unless you are comfortable with the fact that you and your friends are all secretly horrible people with filthy minds. You can avoid some of the risk to your sanity and others' by playing only with PPC decks, if you so choose. They're still rated at least PG-13, though. Lily Winterwood is responsible for creating the first PPC-themed CAH deck, but several more have been made since.
