Product title: Vampire Squid Cards Crabs Adjust Humidity - 4-Pack (Vol. 1-2-3-4)
Product description: This is a 4-pack of Volumes 1, 2, 3 and 4 of Crabs Adjust Humidity, sold together. Volume 1: Love Cards Against Humanity, but even with the official expansions find yourself playing the same cards over and over again? Enter Crabs Adjust Humidity , a crappy little third-party, unofficial, unauthorized expansion card set that blends seamlessly with the original game and adds 112 morally-questionable new cards to play. Volume 2: Get a nostril full of that intoxicating New Card Smell with Crabs Adjust Humidity: Volume 2 . We've dug deep into our therapist's notes and angsty, forgotten LiveJournal blogs to bring you another 112 cards that--were you to play them in public--would probably get you put on a list of some kind. Volume 3: History doesn't have a great record when it comes to third editions. Notable examples of how things go wrong include The Hangover Part III, the Third Reich, and my mother's third child, Stephen. Despite that, with Crabs Adjust Humidity: Volume Three we're yet again casting aside our filthy metaphorical undergarments in order to expose the twisted, glistening undersides of our damaged psyches. Here's another 112 cards so ill-advised, acting them out could get you thrown in federal prison. Just like Stephen. Volume 4: Comedy isn't easy. In fact, studies have proven that it's the most difficult and challenging of all human endeavors. It takes experienced, trained professionals to produce the kind of high-potency, refined humor that generates sustained, clean-burning laughter without unpleasant side-effects. The result of months of dedicated research and extensive animal testing, Crabs Adjust Humidity: Volume Four is comprised of 112 cards representing the very pinnacle of tasteless, juvenile humor.
